I dont work with Revive, but for my custommer, I try update Revive 3.05 to latest version.
1 - Install Revive Latest version and other environment. All OK!
2 - Copy the database Revive to new database and change my conf to new database (copied from old version) - Work!
3 - My custommer now work fine, I believe that problem was PHP and deprecated files in old environment (worked with subfolder, now, master domain)
4 - How update manual MySQL to enjoy all feature of latest version? We are using new files, all working, but dont see all feature from Revive.
