Whenever I add a function block to a Composer page it loads for a while (and according to the log Composer pages are stored in the database), but then I see a message saying "You are not allowed to view this content block." instead of the function I added.
I've tried resetting all page permissions, and I've looked in the log files to see if I can see anything going wrong, but everything appears to be working fine. :/
Has anyone else seen this?
Hmm, it seems the error stemmed from the content functions overriding their Render method in order to add a surrounding div element when in Composer edit mode.
After reverting to a non-modified Render method the functions display properly again. :/
