Out of the blue I get 5000 emails last night instead of 500. I find MagicSpam is Disabled and a message saying "Your licence key is currently empty". I try to re-install but I get: "PleskFatalException: Unable to connect to database...etc...Too many connections".
Nobody has touched the Plesk or MagicSpam configuration for weeks.
Can anybody help?

This issue has been escalated to email. The latest response is included here in the event others experience this issue:

"There are may be a couple of issues here. First, please remove your current module and install the latest version which Parallels uploaded to their download site. The latest version solves a licensing detection issue, that may be part of your problem."
