I’m sorry you’re hitting difficulties, Vincent.
I also see you noted having ran through our standard troubleshooting steps (reverting to a default theme and deactivating all other plugins except for The Events Calendar and Community Events, in this instance) – can you confirm that didn’t highlight any conflicts that might be at work?
Can you additionally try switching to the Default Events Template and, if you have made no changes to our templates, could you remove or temporarily rename the tribe-events folder within your theme?
Let me know how you get on!
