Hi 4ice,
Thank you so much for the reply.
The truth is, I don't think the sysadmin can do an upgrade without updating more than just MySQL.
How much tweaking would be needed? I'm hosting on a shared platform but have my own .cnf file for mysql and my own .ini file for php which will affect only my virtual container.
I'd really love to be able to get OST working there rather than have to /try/ and code a ticket system myself.
Thanks again for your help!
