We recently had to turn off cron for a few days, and now we’re getting multiple “Unknown column ‘post_parent’ in ‘group statement'” errors when another site on our multisite attempts to import from the main site. According to the import history for the child site, several imports have failed, but the last automated import succeeded. I used the “Run import” link in the scheduled import, that import reportedly succeeded, but also generated errors.
The log reports that the query was:
