Lacking Some Icons on Server 15.0.5

Nextcloud version 15.0.5
Operating system and version Debian 9.8
Apache version Apache/2.4.25 (Debian)
PHP version PHP 7.0.33-0+deb9u3

Dear All,

After serveral rounds of updates, my Nextcloud server misses certain icons, such as the three dots to the right of the sharing section where one can set the share permissions. Other icons are shown only partially, such as grey circles and grey boxes with rounded edges lack content, such as the plus sign in the circle on top of the folder tree page or the upload indicators in the boxes on theming settings.

I did try to make temporary theme changes (such as change color in theming settings) in order to regenerate cached content. That did not help.

Please point me to the right direction in order to solve this isse.

Regards,

Michael Schefczyk

Hi, what is the HTTP error code when your browser tries to get them? (if it tries) you can find that in developer tools.

Thank you! My apache configuration did contain a content security policy on top of what Nextcloud does itself in this direction. Removing my own CSP solved the issue.
