[kesselb]

Does the file /srv/http/www/nextcloud/lib/composer/composer/../../../lib/private/Accounts/Hooks.php exist?

[produnis]

Hi kesselb,
no, the file does not exist.
the folder is just empty...
how could that be?

[produnis]

fsck threw several errors for the harddrive...

I moved the files from a fresh nextcloud.zip to my installation and now it works again.

How can I be sure that other files are not missing, too?

[kesselb]

Login as admin user into your Nextcloud and access 
http://example.com/index.php/settings/integrity/failed 

I think this should print some warnings if files are missing or corrupted.

[produnis]

"no errors have been found"
thx kesselb!!!
