My last automatic backup failed a few days ago.
I have just successfully manually performed the backup, but, I noticed that a Warning appeared, which is the same warning that showed up the previous 4 times it backed up.
It reads “Table ‘wp_dprv_post_content_files’ has no PRIMARY or UNIQUE key! Backup of this table may be inconsistent; some rows could get missed. See FAQ for more information.”
My site is http://www.ourhometools.com
Can you please tell me what this warning means, and how to resolve any issues?
