Anyone able to have a look at this please, started the learning curve and now I am a bit stuck. here are the logs and sys.info and ver. 1.Cant access config, just get server 500 error 2.Goes wrong when monitored email setting installed. (other SMTP) ssl none,port25 Pauses for ever with the status curser in perpetual motion. Only way to stop is is logging out. 3. Look at the active connections on the database, looks wrong although i don’t really know why!
