Can't change styles..

[BowlingTracker]

Hi.. I've recently updated my forums from 3.7.3 to vB5.1.1 on a test server. All was working fine, so I wanted to try a few different styles.

I install this one from Sukagwe. Uploaded the zip, as directed. It had two styles xmls to try. I tried the non gradient one first.. didn't like the red glow under the top tool bar.. so then in imported the gradient one. Didn't like it either for the same reason.

Then I installed this one, also by Sukagwe. There was no zip to upload, so I just imported the gradient xml one. When I tried to select the theme in the forums, it reverts back to vB5 Default.

I tried switching back to the first one by Sukagwe (it was still installed), but it would still always revert back to vb5 Default. I've tried installing a few others and even just added an empty style called test. But can't select it in the forums.. it always reverts back to vB5 Default, regardless of what them is selected.

Have I completely screwed up the theming system? Any idea's why I can't change themes?

I have since deleted all the custom themes.. even the incompatible vb3 and vb4 themes. All I have now is the vb5 default and the blank "test" I created by clicking "add new theme". Still can't change to the "test" theme though..
