After I upgraded from 1.26 to 1.29 certain UI elements seem to have reset their scaling and/or color. For example, the bar at the top now has black sections with white text when they should be yellow sections with black text. Are there any known causes of this? How should I troubleshoot this? I've tried changing the CSS to match but it doesn't seem to affect the kin itself. 

For reference, I am trying to make this page https://wikiapiary.com/w2/index.php?title=Main_Page look like this page https://wikiapiary.com/wiki/Main_Page
