Link to your site, as there must be something causing that – it works out-the-box.
Hi,
I identified the problem. You were right that it works on our other websites when we switched them over for a test. So I suspected it might be one of the plugins we have installed at http://www.lifeisaforkintheroad.com which we don’t have on our other sites.
Turns out the culprit is WP-Copyright Protect which prevents people from copying our blogs. When I turned this off, the Customize function worked fine with the preview coming up and the menu working as it should. When this plugin is activated, the Customize function will not bring up a preview of the website and keeps going through a loop.
This was also true for other Themes we temporarily activated. I will send a message to that plugin telling them about this issue. It’s a critical plugin for us because we had someone steal our content and post it as their own on their blog.
Thanks for getting me to look at this a bit more.
Don
