Server: Favicon in NC11..NC14 not working

[caco3]

Still not working :(

Details see

• https://github.com/nextcloud/server/issues/3428#issuecomment-323206431
• https://github.com/nextcloud/server/issues/2900

[juliushaertl]

@caco3 Is there anything in the log files?

The original error from https://github.com/nextcloud/server/issues/2900#issuecomment-298232138 should already been fixed with https://github.com/nextcloud/server/pull/4888

Now, when I enter https://*.ch/index.php/apps/theming/favicon/files?v=9 in the browser, I get a message that the graphic contains errors:
Strangely this text can not be copied from within FF...

Can you check the output file with some other browser or curl?

[hawkeyexp]

Possible targetting same problem: when theming nc with custom logo favicon is not changing only logo change is ok on welcome etc. The crazy part: 2 mashines running nc13rc1 (after update to rc2 no change) - one it works one it fails.

[caco3]

@juliushaertl No, there is no NC log entry.
Please see https://github.com/nextcloud/server/issues/2900#issuecomment-298189757 where I already provided a lot of additional information. By then there was an error listed in the log, this indeed seems to be fixed now, at least there is no log entry anymore.

How ever when I call the favicon directly (https://owncloud.ruinelli.ch/index.php/apps/theming/favicon/settings?v=13), I still get the error that the image is corrupted: "The image cannot be displayed because it contains errors".

Looking onto my servers filesystem, I see that there are many favicon files, but they are all empty:

I guess the theming app fails to generate them, so they stay empty and fail to be displayed.

My expectations:
In case the theming requirements are not met, there should either be a fallback and/or a warning.
On another server (Synology), I see this message: "Install the Imagemagick PHP extension with support for SVG images to automatically generate favicons based on the uploaded logo and color" so its clear to me that it will not fully work.

[joachimmathes]

I have the same problem with Nextcloud version 13.0.0: https://mathes.punkt.cloud/apps/theming/favicon?v=9

[ssnelgrove]

Same thing on my site 13.0.0

[juliushaertl]

@caco3 Could you check if the following command shows that your imagemagick setup has svg support enabled: identify -list format | grep SVG ?

[caco3]

@juliushaertl Sure:

> identify -list format | grep SVG
     MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
      SVG  SVG       rw+   Scalable Vector Graphics (XML 2.9.7)
     SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (XML 2.9.7)

[yrammos]

Confirming the issue is still pending (and burning).

[BonziBuddyMonkey]

Can confirm the problem still persists.

[caco3]

@juliushaertl Any news on this?
Still failing on NC13.0.5.
Is there a way to tell the theming app to regenerate the image files in appdata_5083050d6af67/theming/13/?

[kesselb]

I tried to reproduce this issue but works for me on linux. Maybe unrelated but @caco3 and @joachimmathes are both running their nextcloud on freebsd. What about you @yrammos @BonziBuddyMonkey?

[yrammos]

@danielkesselberg I'm running my instance on Ubuntu 16.04.5 LTS.

[BonziBuddyMonkey]

Im running on ubuntu 18.04

[kesselb]

Could you add some more information about your setup? (e.g. https://github.com/nextcloud/server/blob/master/issue_template.md)

[BonziBuddyMonkey]

Its not completely filled out, as im not sure what this snap version uses.

Steps to reproduce

1. Install from newly realesed snap install nextcloud) I used to have it installed from via the guide on github from my old server, where the favicon worked fine.
2. Load Nextcloud in web browser
   Expected behavior
   The browser should show favicon that I have selected from themes.
   Actual behaviour
   Show the standard blue icon

[kesselb]

@BonziBuddyMonkey do you uploaded your own custom favicon? Favicon auto-generation does not work with snap package (see https://github.com/nextcloud/nextcloud-snap/issues/592). I guess its unrelated to this issue but your are running out of memory. You should increase the memory limit (https://github.com/nextcloud/nextcloud-snap#php-memory-limit-configuration)

[yrammos]

Steps to reproduce

1. Change theme in the NextCloud GUI (no command-line tinkering).
2. Open an incognito window in Safari or Chrome.
3. Clear browser data (Safari or Chrome) — probably unnecessary after #2, but some browsers are known to cache favicons aggressively.

Expected behaviour

The browser should display a favicon derived from my theme.

Actual behaviour

The browser displays the standard NC favicon.

Nextcloud log

File is too long to paste here but grep didn't indicate any favicon-related issues. I believe they were all linked to unsuccessful login attempts and a few application installs.

Browser log

Browser log

Nothing special in the log (no errors in the console, for example). Worth noting that the HTML downloaded by the client refers to href="/core/img/favicon-mask.svg", which is the standard NC favicon.

[kesselb]

When you view the page source there should be a link like this:

<link rel="icon" href="/apps/theming/favicon/files?v=15">

What happens when you open "href" in a new tab?

[yrammos]

On both Chrome and Safari I get this icon:

This generic icon is the one displayed by Chrome; apparently due to aggressive caching, Safari insists on using the NC logo as favicon. Importantly, neither browser displays my custom icon.

[yrammos]

By the way:

$ identify -list format | grep SVG
     MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
      SVG  SVG       rw+   Scalable Vector Graphics (RSVG 2.40.13)
     SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (RSVG 2.40.13)

[alexanderdd]

Weird. I have this problem on one cloud that I manage ("cloudA"), but not the other one ("cloudB"). (They run on different hosting providers but I dont think that makes a difference..)

cloudA: nextcloud 13.0.5, theming 1.4.5
I set custom icon and colors. Later I noticed that there is no favicon. Disabling the theming app gets the (standard) favicons back. Enabling the theming app makes icons disappear again.
@danielkesselberg opening that href says "graphic cannot be shown because it contains an error"

cloudB: nextcloud 13.0.1, theming 1.4.5
everything works as expected. enable theming app. set custom color and logo. custom favicons are created. disable / enable theming app, everything works as expected.

should I get some more info or try something in particular?

__edit__: I have an idea. I installed the passwords app and found this in the error log:

ImagickException: not authorized /tmp/magick-58491xog6YlbhMk95' @ error/constitute.c/ReadImage/420
OCA\Passwords\Exception\ApiException: Internal Favicon API Error

[yrammos]

The passwords app cannot be a causal link because I don't have it installed...

[TomTurnschuh]

I also have no favicon, now on NC 14.0.1.
However, and this might be interesting, it is only missing in Firefox (for Windows, on different computers). On other browsers it is there.

[magikmw]

I also have this problem and like @TomTurnschuh it's manifesting only on Firefox.
A Chromium derivative is displaying both colored default favicons and a custom one generated from logo I use on a different server.
The link to a favicon in page source from Firefox shows the generic icon from this comment above https://github.com/nextcloud/server/issues/7945#issuecomment-412540091.

Servers are v. 14.0.3 with theming 1.5.0 and 13.0.7 with theming 1.4.5.
Both CentOS 7.5.

On both:

identify -list format | grep SVG
     MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
      SVG  SVG       rw+   Scalable Vector Graphics (RSVG 2.39.0)
     SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (RSVG 2.39.0)

[caco3]

@TomTurnschuh @magikmw I am not sure if you guys see the same issue. It might be a different problem!
Please check if the icons got created as expected. In my (and many others) case, the icons are not generated at all, their size is 0 bytes, see https://github.com/nextcloud/server/issues/7945#issuecomment-359178010. Also there will be shown a server error, see https://github.com/nextcloud/server/issues/7945#issuecomment-365562927

Since this is a server error, it does not make sense that it works in one browser but not the other!
If your case is different, please open another issue for it and provide more details.

[caco3]

@juliushaertl Can you please an answer to my question on https://github.com/nextcloud/server/issues/7945#issuecomment-412216117?
Also, in spring I provided the required information (see https://github.com/nextcloud/server/issues/7945#issuecomment-388896660), but it seems nobody really investigated the issue. The issue was first seen on NC11, now we are on NC14! Also I no longer am the only one having that problem! I would be happy to help investigating and solving it, how ever when the questions are not answered, that is not really possible!

[juliushaertl]

@caco3 Sorry, this somehow slipped my radar.

Is there a way to tell the theming app to regenerate the image files in appdata_5083050d6af67/theming/13/?

Regneration will happen every time you change the color of your theme.

identify -list format | grep SVG
MSVG SVG rw+ ImageMagick's own SVG internal renderer
SVG SVG rw+ Scalable Vector Graphics (XML 2.9.7)
SVGZ SVG rw+ Compressed Scalable Vector Graphics (XML 2.9.7)

That looks all good to me. I'm a bit out of ideas why the gernation might fail without errors and put empty files there. Maybe someone else from @nextcloud/theming has an idea?

[caco3]

Ok, I re-added now a new logo.
Interestingly, this solved the issue for me now!
The folder 13 in appdata_*/theming/ got replaced with the folders 15 and images. They contain the logo and a favicon.

[mathiasconradt]

I added a favicon (gif) and it shows in the browser tab, but it does not show in the bookmark toolbar, even after cache clearing. Tested with IE and FF. NC14.0.3.

@caco3 My guess would be that at some point there was an error storing the files. I would actually close this, since we weren't able to reproduce this and it seems to work fine now for you.

@mathiasconradt Please open new issues next time. However this is not an issue with Nextcloud but with firefox caching the favicon. Maybe this will help: https://stackoverflow.com/questions/37859753/refresh-favicon-in-bookmarks-firefox

@caco3 Feel free to reopen if it occurs again.
