OK- ran the check. The results of what is missing:
"Database reports it is version 2.0.22.
Required configuration keys allow_autologin, max_autologin_time, max_login_attempts, login_reset_time, search_flood_interval, rand_seed are missing!"
phpMyAdmin is installed (part of the hosting service's value adds)- but I have no idea where, and what values should be created in the db. Anywhere I can find a "phpMyAdmin for morons" guide?
