Forum:Monobook logo has disappeared

At w:c:tardis, our monobook logo — i.e. the one defined by — no longer appears on pages. I can't figure out what happened. There's just nothing appearing on the top left of our pages, when viewed in monobook. I've taken a few steps to resolve this, but nothing's worked. I've moved the original contents of to, then deleted wiki.png and started over with a completely fresh start to the page. I've looked in Firebug to see if the page is referencing the correct file. Hovering my mouse over the style definition for that part of the page reveals the new logo, so I'm guessing it is referencing the correct URL. I've changed the new logo several times, ultimately bringing it down to the exact recommended width for monobook of 135px.

None of this has done anything.

I notice that other people's wikis still seem to be happily displaying the contents of wiki.png, so it's definitely something about our wiki that's at fault. Anyone have any ideas/memories about how to make a hidden monobook logo reappear? 15:40:28 Sat 11 Jun 2011


 * The problem is your MediaWiki:Common.css:

/* LINK COLORING */

a:link { background:none !important;text-decoration:none;color:#2f2cb8 }
 * since you are forcing a background:none !important and the logo is placed inside a link as a background image, you are overriding the wiki logo. --Ciencia Al Poder (talk) -WikiDex 16:09, June 11, 2011 (UTC)


 * Wow, thanks for that speedy and accurate diagnosis. That was totally the problem.  Since you seem to know something about monobook, I wonder if you could explain why our front page, tardis:Doctor Who Wiki displays the logo differently than any other page in monobook.  It's being truncated on the right side, presumably because of the odd way in which the buttons at the top are overhanging the left margin of the article space.  I imaging if I could cure that overhang, then the logo would pop back into place.  Got any theories what might be causing this?   18:25:44 Sat 11 Jun 2011


 * The problem is one or more HTML unpaired HTML tags, like an unclosed  or an extra   without the corresponding starting one. I tried to figure out what the problem is but failed, since it uses too many templates and it's a pain to check every one. Maybe you could subst all templates (placing subst: before all of it's names, like  ) on a sandbox page to check the HTML tags. --Ciencia Al Poder (talk) -WikiDex 20:01, June 11, 2011 (UTC)


 * Well, yer two for two. Found it pretty quickly after you pointed me in the right direction.  Thanks again for your quick and accurate help.   21:01:35 Sat 11 Jun 2011
