I first had the site owner run the manual query:
Code:
alter table `session` max_rows = 25000 avg_row_length = 532
That didn't work.
Then I directed the owner to run the manual query:
Code:
set @@max_heap_table_size=16777216
That didn't work...and I began to suspect the db would need to be restarted.
I directed the owner to the following link:
How to edit the MySQL my.cnf file
I was informed by the owner:
Quote:
That's not possible as we're not running on a VPS or dedicated server.

Okay, well I then suggested contacting the host for assistance. After waiting nearly a week for them to reply, they finally edited the my.cnf file, and we appear to be back in business.
We still have no idea how the MySQL variable was changed in the first place.
