Hi joshuah,
I’m sorry that following those steps has resulted in difficulties. Making a backup is a valuable precaution to take before making any sweeping changes to your site (such as mass deactivating plugins) and we’ve updated our Testing for Conflicts page to make that as clear as possible.
I’m guessing that in this case you didn’t make a backup – but it could be worth checking in with your web host (sometimes they make automated backups) or even with your designer/developer if you use the services of such a person or business to help manage your site.
Unfortunately there’s not a lot we can do to help in terms of reconfiguring your widgets, etc, but we’d certainly be happy to assist with the initial problem. Can you link me to one of the events you tried to set as a recurring event and perhaps share a screenshot of the recurrence settings?
Though you can’t upload screenshots directly to the forum you are welcome to drop a link in to any images hosted on a service like Droplr or Dropbox (or of course you could upload them to your WordPress site).
Thanks!
