Thread:Project:Support desk/WikiEditor toolbar icons are missing/reply

You have updated to 1.22.4.

The problem is that in the wiki editor toolbar the actual images for the icons are not displayed.

When I check that with Firebug, then I see that there is a background image (some sprite) assigned to each of the buttons, but this image is not used:

Instead, this background style takes precedence:

background-image: none Applied rule:
 * 1) content a:link	{background-image: none; }

When I manually disable this rule with Firebug, I see the icons again.

Now you need to find out, where this style is coming from. It might help to set the MediaWiki resource loader into debugging mode for that; however, just with adding &dbug=true I did not manage to see the toolbar at all.
