Having the same issue with one recurring event going out of control 26,000 occurences. Locking up my site where I can’t perform backups, site performance is slow, etc.
I tried step one of this process and can not see any results…
Here is the procedure to follow:
Using phpMyAdmin, run the following SQL script: https://gist.github.com/elimn/a998d7b67f6166dab5e17ec071eb35ee – this will likely return 1 or maybe 2 event IDs that have the runaway recurrence issue
Edit/update those event IDs in WP Admin. This can usually be accomplished by adding a space to end of the event description and hitting update. This will cause it to rebuild the recurrence and remove the offending entries.
If that does not work, then you can use the following SQL script to delete all recurrence of any event id: https://gist.github.com/elimn/e5de5d2037678de0b926c307022571c5
If I privately send you my login credentials, can you help me clean this up?
Many Thanks For the GREAT Plugin!
