Is there a definite solution for the "duplicate key" errors? Had been running Orban's original Sphinx solution for 2 years... Migrated site to new servers, then implemented Orbans version .1 solution. Now I'm getting these errors like many others in this thread:
MySQL Error : Duplicate entry 'c7ff13943221ad39284628de371af860-lastpost-DESC' for key 2
Error Number : 1062
I've tried repairing, optimizing, and truncating the table, No change
Someone mentioned modifying the php to read "REPLACE" instead of "INSERT" ? I'm running 3.6
Thanks!
