re: Whenever I click on the “Templates” link under “Connections” in the left-hand side bar, I get the following error: “The page cannot be displayed because an internal server error has occurred.”
Why is this feature/function not working?
Never had anyone had such an error before… I can not even guess as to why you would receive it. I would need a temp admin account so I could log and take a look.
re: This problem appears to be happening with the new template customizer.
Could you give me details on what gives you this impression? I ask because there seems to be more than just the error you’ve already stated. As the Template Customizer files/support is not even loaded until you click the Customize button for the template being customized.
re: Are there some features that must be enabled (server-side) to allow the template customizer to work properly?
No. It uses the same API/s (code) that WordPress uses for the Theme and Widgets customizers. Your WordPress version is up to date, correct?
