Category operations 'disappearing'

[Sewwy]

Hello,

since having upgraded Coppermine to the current release, I've not been able to make any modification to the operations side of the categories. The buttons are technically loading, but after the page has completely loaded, all of the buttons essentially disappear, becoming unclickable and invisible. I can see them whilst they are loading (at least, I can see the "image loading" square) and am able to click on this successfully and produce a result, however once the page is properly loaded, all functionality disappears.

This is the current theme I'm using, and I managed to screencap it whilst it was in it's loading phase. As you can see, there are plenty of blank spots where there SHOULD be buttons, but aren't. I've also tested it in another theme (http://27.media.tumblr.com/tumblr_lmbhpwWYfU1qiyahzo1_400.png) and have the same problem.

It'd be fantastic if anyone had any suggestions or solutions.
