[Plugin: Event Calendar / Scheduler] not possible to save configuration

Using WP 3.3.2

I reverted to Scheduler version 2.3 after updating to version 3.0 (which produced errors on the configuration page & didn’t show the calendar on the site – there is another thread for that)

So after erasing the updated folder & restoring the 2.3 folder the calendar now shows, but I cannot now save my configuration either and the upcoming widget no longer displays any events (probably as there is no number defined for the number of events in the widget).

I fixed mine by finding an installation that had a working version of 2.3 and ran the following query on the DB

SELECT *
FROM lgbe_options
WHERE option_name LIKE '%schedul%'

Then copied the values to my broken version & I have 2.3 working correctly again.

I am getting this error usinge WP 3.32 and Scheduler 3.0. I cannot find the log file. Not sure where to go to make changes to or fix the error. I’m sure there are more posts on this issue.

Not only can I not save the configuration file, the calendar is useless, I cannot click on any date that does not already have something scheduled. So as far as my use for this calendar I’m at a dead stand still unless I can get a fix for this issue.
