Hi Tessa!
I’m sorry you are experiencing that issue. Let me help you with the troubleshooting.
I am able to see you main events page in the link you provided. Were you able to solve this issue?
If you are still having problems, please enable WP_DEBUG and WP_DEBUG_LOG ? This will create a debug.log file inside the /wp-content directory.
After that, try reproducing the issue a few times, so that in case there is an error, it will be saved into the debug.log file. Please share that log file with us so we can see if any problem from there.
Let us know about it.
Thanks,
Victor
