Hi Pavel,
Thanks for your feedback.
I automatically clear all cache (including Jspeed) after every configuration change. I have a plugin that does this to make sure.
I have disabled Jspeed for now.
Joomdonation responded that Jspeed was indeed causing some of the problems with Event Bookings. Now my registration function is back, but I am having them look into why Event Booking pages are so slow to load now. Sometimes they load quickly and properly, but other times they do not. No other component pages are doing this. Arghh!
JoomLMS (www.Joomlms.com) is looking at issues that appeared after the template update.
Pavel, do you provide consulting (for hire) to fix issues with Joomshaper conflicts like this? If so, please contact me at [email protected].
