Rollback / Re-install mlf 2.4.6 with backup fails (General)
I cannot delete this topic so i'll post the solution which seems to work for me:
By comparing the data in the various fields it turned out that the userdata table in my backup was missing the entries_read column. After deleting it, the import passed through smoothly and i re-created the column manually.
I have absolutely no idea why there was a difference for the new and backed up data, both claiming to be version 2.4.6.
