CMS Unable to Configure Widgets
 

I am unable to configure my widgets. On the Widget page, when I click the Configure link, a partially transparent gray page is displayed for a few seconds and then the Widget page reappears. When the gray page is showing, if I maximize the browser, I see the following in the center of the page:

I have vBSEO 3.5 installed but the behavior is the same even with all products disabled.

Also, my 'Friendly URLs' option is set to 'Standard URLs' as required by vBSEO.

Any idea how to fix this?

Thanks,
