Admin Forum:Logo backgrounds not working anymore...

My upper banners are all gone:


 * http://siouxsie.wikia.com/wiki/Siouxsiepedia
 * http://san-francisco.answers.wikia.com/wiki/San_Francisco_Answers
 * http://marapets.wikia.com/wiki/Marapedia
 * http://philadelphia.answers.wikia.com/wiki/Main_Page

I already checked in the CSS validator, no errors at all. Does this have to do with a recent wikia change? They were all working a few days ago, and my absent mindedness is to blame for not noticing exactly when they went poof! I do have a hint from this from December 3rd, it is gone in the screenshot, so I am guessing that's when I lost them? Any help is appreciated! --Liliana (my talk). 03:53, December 15, 2012 (UTC)


 * Can you provide links to the CSS? -- Fandyllic (talk &middot; contr) 17 Dec 2012 5:42 PM Pacific


 * Sorry I didn't know I received a response yet. Well, yes this is what I've had for at least a year in them:


 * http://philadelphia.answers.wikia.com/wiki/MediaWiki:Wikia.css
 * http://siouxsie.wikia.com/wiki/MediaWiki:Wikia.css
 * http://san-francisco.answers.wikia.com/wiki/MediaWiki:Wikia.css
 * http://marapets.wikia.com/wiki/MediaWiki:Wikia.css


 * I don't understand why a code will stop working like that all of a sudden. --Liliana (my talk). 12:34, December 21, 2012 (UTC)
 * Can you explain what it used to look like, and specifically what part of the source code is not working anymore? I'm guessing it's something to do with the wm-1, wm-2, wm-15 classes. Eg, on the front page of the Marapets wiki, I see you have a -, and your wm-15 class just sets a background image - so what you've got there is a "-" character with part of the background image behind it. Did it used to load the entire image there or something?-- Category:Acer4666  17:42, December 21, 2012 (UTC)


 * Thanks for helping, but no that's not it. That's been working in wikia wikis since the days of the Monaco skin, persistent piece of coding if I should say so.  Note all that this code affects (see image) works perfectly.  It is hard to supply an image of a piece of coding that is /NOT/ showing an image; when the image is not there.  But specifically, it is the line where ".WikiHeaderRestyle" and ".WikiHeaderRestyle .shadow-mask" should show this image on the background of the upper wiki menus here to be exact.  Sorry I don't have a working screenshot that I know of.  --Liliana (my talk). 01:26, December 23, 2012 (UTC)
