THANK YOU for finally fixing the problems I (and many others) had with getting 404 Not Found on pages for views that did not have an event . THANK YOU for finally fixing the messed up sidebar formatting on pages for views that did not have an event. By updating to version 3.11.1 / 3.11.2 my problem is no longer a problem.
Are missing semicolons in templates causing my funky sidebars?
I installed the 3.11.1 and 3.11.2 updates on my test site and it is all working correctly. It had nothing to do with my theme at all. You finally identified and fixed the bug.
SUGGESTION: I notice in today’s forum that some people are reporting problems based around these things that they weren’t seeing before. I suggest that Support tell them to delete all the workarounds for 404s and sidebar formatting they may have in their child theme functions.php and tribe-events folder. These are no longer necessary and may be conflicting with your bug fixes.
