Huge problem with stylevars, please help!

[CNWPhoto]

I upgraded to the newest version of vBulletin, and now my stylevars won't work. When I click on any option, instead of loading the adjustments, it loads a 404 message in the window. I e-mailed a support ticket, but evidently you only get 30 days of support after purchase....

This is what they told me, but no info on how to fix it: That is a valid url, however your wordpress install seems to think its a 404 page.

Thank you in advance for your help!!

So whenever you try to edit a stylevar, you get a 404 when you click to save it?

What is in your error_logs (if you don't know where they are, ask your host)?

Have you tried disabling your plugins?

Have you tried removing the .htaccess from your root directory to see if that is the problem?
