1. Can't view Simple view of Recordset.
-- Just remove the "LIMIT" statement manually before switching to Simple view.
2. Javascript error in /configuration/ServerBehaviors/PHP_SQL/DynamicSelectList.js - it doesn't actually exist. (see attached).
-- This should have been copied into that folder during installation. Please post a US phone number or Skype contact information and I'll call you to do screen sharing and investigate what might have gone wrong. Possibly a conflict with an older version of the extension installed.
I'll look into your other issues during a screen sharing session as well.
