I’ve got the same problem here…
I’m getting 502’s when the plugin is activiated. While I was inpsecting it over command line I found: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 3200 bytes) in /home/fa652097310995/html/wp-content/plugins/the-events-calendar/common/src/Tribe/Main.php on line 211
This has only just started happening this week… did you update anything to make it require more memory?
