Good afternoon and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the issue you experienced.
I would love to help you with this topic.
I am really glad that re-saving your permalinks fixed things for you.
On some installations, this is required after updates.
We are looking into this to find out why.
As per your suggestion, that would be very awesome. Thank you for bringing this up.
For the time being, since we do have a known issues page: https://theeventscalendar.com/known-issues/
I am going to suggest that it gets updated more frequently. This would totally help.
You are welcome back in our support forums any time 🙂
For now, I am going to close this thread.
Have a great week!
Geoff B.
