Duplicate column name ‘post_date’

We recently had a strange database error on a site that uses Events Calendar Pro. The error logs were chock full of the following error:


Duplicate column name 'post_date'

Turns out there’s a bug in the plugin that they are trying to fix. In the meantime, here’s three temporary fix options:

  1. Uncheck: Events > Settings > General Tab > “Recurring event instances”
  2. Uncheck: Events > Settings > General Tab > “Include events in main blog loop”
  3. Downgrade both Events Calendar Pro and The Events Calendar to 3.11

We ended up going with #2 and it solved the issue.

Update: I had to also uncheck the box for ‘Recurring event instances.’ The bug was conflicting with the Tag Cloud widget.
