Thank you very much for helping me.

quick noob-questions: which format does your logo-file have? have you tried different formats?

3

I’ve tried png svg and jpg file.

4

ok. one of it SHOULD work, at least (if not all).

ummm… other than that… i dunno. i thought it could have been a problem with the formatting of the logo because of

how do you run nc? dockerized? snappish? vm’d? or directly? which environment?

5

maybe it has something to do with: https://github.com/nextcloud/server/issues/18328 ? could you please check that out?

6

OK, I think I should upload the logo again in another format.
I just dropped the nc file directly into the directory of the website.

7

Now I can tell you that I have tried all common image formats: jpg, jpeg, png, svg and even gif.

Might be some issue with permissions.

  • Are the paths in the nextcloud directory writable to the webserver user (www-data, http or whatever the username is on your system)?

  • Is there anything similar to this in your config.php:

array (
              "path"     => OC::$SERVERROOT."/apps",
              "url"      => "/apps",
              "writable" => false,
      ),

I am having the same problem as well.

Following is the log file. Anyone can help?

enabling imagic from the php modules solved for me the problem

I installed imagick, but I’m still having issues. I restarted PHP and I’m still getting the errors. Did you do anything else to bump once you loaded imagick?
