I'm trying to set up a basic Sitecore Multivariate test in Sitecore 6.5 (rev. 120796), but have run into the same error, repeatedly. The error occurs when I am in the Sitecore "Page Editor" mode.
First of all, I'm not able to "select" each of the content items on the page, and I'm not really sure why that is the case. But, I may not be 100% clear on what the requirements are for configuring a content item for an A/B test in Sitecore.
In the Sitecore Page Editor, when I highlight a content item and click the "red boxes" icon to bring up the "Test the Component" dialog, the "Test Content Item:" just says "[Not set]". When I then click the 3 dots to attempt to browse to a content item, I get a pop-up error message that simply says "an error occurred."
What are the requirements for a content item to be defined as a test variation in this version of Sitecore? Or, is there something else that needs to be done before attempting to configure the test variations in the Sitecore Page Editor?
