This is just not working at all. Numerous file not found errors (HTTP 500 and yes I've checked all links etc) and the same error previously reported.
I've tried completely stripping out and re-installing but still with no positive result.
I've backed up the previous database files so would you advise starting completely with a new database and re-install with 450? Or go back to the basic 4.0 version and stepping through 4.1 to 4.50?
Your opinion highly valued!
