I D/L ed the latest zip file from the Download Area in my account at WebAssist..
I then uploaded to a completely brand new directory on my domain so we could have a fresh install.
The heading for the PowerMessenger Welcome Install screen no longer gives a Version number, But the explanatory text underneath it unfortunately still says:
Welcome to the PowerMessenger 1 Installation blah blah blah.
But more importantly, upon successfully completing the health checks and being told that I could advance to the next screen, I promptly got a 500 error which pertains to the page:
(SInce I did not know what else might transpire, I resisted the impulse to copy the file over from the recent successful install!!)
