Cannot use drop down in Styles editor. Was working fine just a few days ago. All other editor options with arrows to drop down work fine. Just purchased and updated to JCE Pro but that did not help. Please advise how to proceed.
The value you had set was not identical to the site url, it was missing the www, so the browser was rejecting processing of the stylesheet because it regarded it as from a different domain or sub-domain to the one loading it.
Just because you're not paranoid doesn't mean everybody isn't out to get you.
