The errors in the browser come from an extension. Could you load the page without any extension enabled? Maybe it's blocking something.

[dorearendil]

Thanks for your input, Morris.
I tried disabling all extensions in Chrome, but no joy.
In Firefox (v63, Ubuntu 16.04) something weird happened.
At first, the same icons were hidden as on Chrome. So I tried restarting Firefox with all extensions disabled... and the icons appeared! So I tried reactivating the extensions one by one -- but none of them seems to break the page anymore... All of them are now reactivated, and all icons are displayed.

Using the Chrome inspector, I noticed that the background-image paths of non-displayed icons don't seem to be found in the CSS. For instance, the main NC logo, top-left:

#header .logo {
display: inline-flex;
background-image: var(--image-logo);
background-repeat: no-repeat;
background-size: contain;
background-position: center;
width: 62px;
position: absolute;
left: 12px;
top: 1px;
bottom: 1px;

In Firefox now, this full path is shown for all icons (even though I deleted the cache)

[MorrisJobke]

background-image: var(--image-logo);

@dorearendil Can you check if the /index.php/css/icons/icons-vars.css returns a proper css file with a list of all css variables? The image-logo should be set in there

[dorearendil]

@juliushaertl Sorry for the late reply.
As far as I can see in my inspector, the only css file that is computed is "cd70-a1ac-server.css".
"Icons-vars.css" doesn't seem to be taken into account...

[juliusknorr]

@dorearendil Any other entries in your nextcloud log besides the webdav errors?

[dorearendil]

@juliushaertl No, only the webdav errors... :(

[juliusknorr]

Can you try to run occ maintenance:repair This should empty the css caches and trigger a rebuild on the next page load.

[dorearendil]

@juliushaertl I ran the repair command, and things seem to be back to normal on all my browsers except for an old version of Chrome (which my system won't let me update). So I guess the issue can be considered solved. Many thanks for your kind advice.
