any updates on this?

[altosch]

In my case it stopped in itself. The messages were appearing in 2 days after upgrade. Nothing since. Don't know why and it seems we didn't lose any files. But there has to be something wrong because it's a PHP error.

[Shuvi-Hub]

i have the same proplem and because of that I can't upload files properly :((

[axheli]

i have the same proplem and because of that I can't upload files properly :((

Yup me too

[Shuvi-Hub]

Ich habe das gleiche Problem und aus diesem Grund kann ich Dateien nicht richtig hochladen: ((

Yup ich auch

like 250 Kb/s and at the end an error/abort or freeze?

[yewkay]

I am having this error as well, it's generating quite a huge log file and masking out the other potentially important errors. Any resolution to this? On NC v19.0.2

Edit: Updated to v19.0.3 still experiencing the same issue

[altosch]

It's back again after upgrade to 19.0.3. The number after hash in the log message has changed from 680 to 683.

Cannot modify header information - headers already sent by (output started at /var/www/nextcloud/3rdparty/sabre/http/lib/Sapi.php:132) at /var/www/nextcloud/apps/dav/lib/Connector/Sabre/File.php#683

[axheli]

@nickvergessen any ideas on this?

[csgt01]

I have the same Error on Linux, Mac and Android Clients.
I can't upload any files.

[papezg]

Same here no sync possible on any platform.

[xmzl]

The same thing happens here, regardless of the client operating system. However, using the oCluod client on Android, the Nexcluod server (19.0.3 on Debian 10) accepts the upload of those files that it refuses if uploaded from the Nextcloud client

[papezg]

By reverting client to 2.6.5 the sync works again. Avoid client 3.x for now.

[boyi01]

Same error in 19.0.3, even uploading via browser is not working...

I did little research, i can upload really smal files some kb, but imgaes some mb are not possible....

[PieterGit]

Same error in Nextcloud 19.0.3. Uploading small text file in browser to WedDav external store is not working.
Frontend says: "Er trad een onbekende fout op." (dutch).
nextcloud.log says "Cannot modify header information - headers already sent by (output started at /nextcloud/3rdparty/sabre/http/lib/Sapi.php:132) at /apps/dav/lib/Connector/Sabre/File.php#683
Uploading same file to non-external storage and DropboxV2 storage works fine.
Uploading in the ios app to the WebDav external storage did also not work (500 error).

I found workaround that worked for me for the webclient. I removed my DropboxV2 external storage and removed the external dir of the WebDav storage. Now it works (both in the ios app and in the webclient).

[xmzl]

With Nextcloud 19.0.4 the situation does not change. Only one line number is different in the error message (#683 -> #690)
Error: Cannot modify header information - headers already sent by (output started at /var/www/html/nextcloud/3rdparty/sabre/http/lib/Sapi.php:132) at /var/www/html/nextcloud/apps/dav/lib/Connector/Sabre/File.php#690

[Infratek34]

Same error for me on Nextcloud 19.0.3. line number is #683
How fix it ??

[j0yze]

Same here. I did a fresh Nextcloud 20.0.0 installation and I get the following, if I upload a file to a shared folder through a shared link:

`Error: Cannot modify header information - headers already sent by (output started at /config/www/nextcloud/3rdparty/sabre/http/lib/Sapi.php:132) at /config/www/nextcloud/apps/dav/lib/Connector/Sabre/File.php#691

But I can upload without issues, if I login with my user account.

[Antimoon51]

It's not a solution, but it is something.. I had the same error since I made an update to 19.0.3. But now the error is gone, after I changed the local network. I don't know how this affects anything, all I know is, that the working network has a better upstream (downstream is equal). I couldn't check yet if it still fails with this error in the other network, but maybe I can test later and will report interesting results.

I'm still trying to find solutions. Everything worked well with the 18.0.x then, from 19.0.3 onwards I can only upload files of less than 1.5 MB. This is as much with the Android/iOS client as it is with the browser. What puzzles me is that I can easily load 1 GB files if I use oClud.de

[prismopensource]

Same problem with 19.0.4 here, using client version 3.0.2 on Windows. No problems at all when uploading files through the web interface.

[sercasbh]

I had the same issue (NC 19.0.4)
I had configure an external storage to a SMB share that was off-line.
I remove the configuration and all works well

[simonspa]

Here is a full stack trace, maybe that helps in understanding the underlying issue. In this case it was triggered by an upload from the Android app:

Hello,

Any update regarding the mentioned error? Im using the 20.0v of nextcloud docker installation and this error causes a lot of issues on the file uploading from clients. Also, the application interface is being so slow when this error appears.

[prismopensource]

Wondering as well, I have that same exact error on our all Nextcloud instances, if there is any way to get more attention for this bug it would be greatly appreciated.

[j0yze]

I was able to fix it on my installation by manually apply some changes.
I found it in the German Nextcloud community board:
https://help.nextcloud.com/t/nextcloud-20-stable-kann-mit-offentlichen-links-nicht-uploaden-und-nicht-loschen/94471/6

[prismopensource]

Does anyone know whether this is fixed in 20.0.1?

[simonspa]

The changes linked from above are in 20.0.1.

[axheli]

im on 20.0.1 and i have not gotten that error yet.

[boyi01]

I had the problem, i could upload any file... after i reinstalled and useing my backup it now works..

[janborg]

I use nextcloudpi and I struggled with the same issue for a while and could finally fix it. I cant say why or exactly since when, but the tmp folder set in the /etc/php/7.3/php.ini (sys_temp_dir = /var/www/nextcloud/data/tmp) didn't exist (anymore).

As my nextcloud data is on a USBDrive, the path to my ncdata-folder is /media/myCloudDrive/ncdata/. So I made a /tmp folder there and set the php.ini to this folder: `sys_temp_dir = /media/myCloudDrive/ncdata/tmp'.

After restarting php-fpm, I could upload again without any problem.

[dzi77]

Until now, I don't have succeeded to solve this issue with headers. This issue is critical as it breaks the functionality of the application and we cannot exchange files. Please somebody assist us to solve this.

Can you give more information? I don't speak German, and I didn't see anything obvious there.

[g4njawizard]

@sbw thats a different issue and doesnt provide a solution for this one we are talking about here.
I also have that issue while trying to sync from debian client to nextcloud.

[sbw]

The error occurs only when syncing large files, for example files of 61MB and 75MB that are modified daily. Small files are sync'd successfully, even when the Windows client reports an error syncing the large files.

The errors first occurred shortly after I applied some updates to the Ubuntu server running Nextcloud on 2020-11-08. I don't know whether that's related. Sorry I don't have more information on that.

[alx-tuilmenau]

I've got some errors of this type a while ago because PHP created it's temporary files on the small system partition instead of the data partition, so this partition was full. After changing the PHP settings to use the data partition, the error was gone.

Can't be the problem here I'm afraid, 20GB available on the partition with the /tmp folder.

[dzi77]

Agree with @prismopensource the PHP has enough disk space to store temp data. I would like also to ask if the other users where have this error are using the plugin Group Folders on their setup.

[prismopensource]

Yup, this instance is almost exclusively using the Group Folders.

[xmzl]

Yes, I use the Group Folder plugin. But I used to use it even when the 18.0.x was working

[githubtmp7]

Yes, I use the Group Folder plugin also.

[dzi77]

In most of the cases, this error appears in my application when the client trying to write data over the size limitation where I have set on Group folders. Furthermore, i have setup Flows and this error appears again when the flows rejecting a file from client where he is trying to upload.

[GillesMocellin]

Hello.
I'm not using Group folders.
I only have problems from the mobile app, in a specific synchronized folder where I do SMS and call backups.

Yes, I use the Group Folder plugin also.

The problem appears when trying to upload many files using any browser other than Chrome. In Chrome everything is ok.

My PHP is configured to use /tmp on a partition with GBs available. Thanks for the suggestion.

I do not use Group Folders.

[githubtmp7]

I found workaround. The error does not appear if I disable the External Storage Support application.

[axheli]

I found workaround. The error does not appear if I disable the External Storage Support application.

I'll give that a try we don't use External Storage Support application so i dont see a point to have it on.

[boyi01]

Did anybody tried to reinstall and use a backup some days aggo? for me that worked perfekt after i had no problems

[sbw]

I can't disable the External Storage Support application, because I'm using it. Thanks for the suggestion.

[githubtmp7]

I found workaround. The error does not appear if I disable the External Storage Support application.

Deeper testing showed that disabling the application does not solve the problem.

[sauces1313]

For what it's worth, I resolved error this on my server by enabling and using the External Storage type SFTP as opposed to FTP (my external storage host is running vsftpd). FYI, the SFTP checkbox under the FTP storage type gave me some problems, unchecking shows the connection is successful, but I got this error when trying to write to the external storage.

Hope you guys get yours sorted.

[xxblx]

I have the same issue. Unable to upload a file to a folder if the folder is an external storage. In my case - local external storage. Uploading to regular account's folders works fine.

Nextcloud 20.0.1

[swp-gh]

Can confirm that taking external storage out of the picture does not solve the problem.
I'm seeing the issue when attempting to upload large files to a "normal" local folder.

NC server 20.0.1
PHP 7.4.11
FreeBSD 12.2

[dzi77]

No its not the solution this. Im not using the external storage and i have this error.
Can someone from @nextcloud assist us?

[AlexG-78]

Same error in the log here. Im on latest Version 20.0.2 using groupfolders. It's impossible to upload any file to group folders. Uploading files to user's local directory works.
I don't know if that is related to this issue, but I've checked groupfolder permissions and it suddenly gives me an empty list. All groups disappeared.

sudo -u www-data php ./occ groupfolders:permissions 1

[pieter-groeneweg]

check your hosts disk quota.

You may run into your limits causing this error that hardly looks like it is related.

[prismopensource]

Nextcloud data folder is on a noquota mounted disk over here.
