==Forcing the server to re-render==
Bypassing your own cache might not be enough if the updated content that is not being properly displayed or is contained in a template or other transcluded page. You may need to purge the server cache of old versions of the page in order for the new material to be visible.
The server can be instructed to refresh its cache of a page's contents with the action=purge URL parameter. Add this to the end of the URL, or in place of the action=edit or action=history.
For example, to purge this page — which forces the latest version of wikimarkup to be rendered to HTML — use:
 http://help.wikia.com/index.php?title=Help:Bypass_your_cache&action=purge
For technical pages you think may need to be purged often, you can create a "purge" template so that you don't have to edit the URL by hand.
Disabling page cachingEdit
As a last resort, you can adjust your user preferences to disable page caching entirely, using
 Preferences→Misc settings→Disable page caching.
See Help:Preferences for more information about this option. Be forewarned: you will be using more bandwidth, make the servers work harder and get worse performance with this option set. Use it as a last resort.

==Image titles in categories. JS fix to allow more than 20 characters==
It seems that only 20 characters (that includes spaces) are allowed to be shown. This prevents easy scanning of the image titles to see what the image is about.
Is there a JS and/or CSS fix for this?
Yes. Insert this code to " Special:MyPage/wikia.js " . 
$(function () {$('.gallerytext a').each(function() {this.innerHTML = this.title;});}); 
To remove the word "FILE:" change "this.title" to: " this.title.substring(5, this.title.length) "
