Xwiki Themes don't apply and there are problems with the import of custom font

Hi everyone,

I’m experiencing two big problems with my XWiki.
First of all when I select and customize a theme and save it, it won’t apply. It’s saved and when I want to customize it again my changes are here but only here.

Then, I would like to import a font style and I tried several solutions but nothing worked. Indeed, I tried to generate a CSS File with Font Squirell and I added it to the CSS file in the “Advanced” panel :
@font-face {
font-family: ‘avenirmedium’;
src: url(‘avenir-medium-webfont.woff2’) format(‘woff2’),
url(‘avenir-medium-webfont.woff’) format(‘woff’);
font-weight: normal;
font-style: normal;
I have also added the text “avenirmedium” in my @font-family-sans-serif:…; line and the HTML command : in the head section (“Look & Feel” → Presentation).

I’m using XWiki Debian 14.7.
If you have any solution it would be very welcome ! Thanks you in advance :slight_smile:
