This situation is not helped when I rush and make elementary usage errors.
Can I offer the following?
(1) The PowerCMS installation I currently have at my new project location had 24 files that did not install properly from Dreamweaver. I had to manually install them; and that still was not quite right, and you had to do a further manual install to fix.
(2) I seem to have for some reason deleted accirdentally or otherwise the PowerMessenger files in this latest project location.
I am due to teach in a short while, but believe I have time to completely delete all files and the database for PowerCMS, and resinatll using Dreamweaver and then begin testing, as if I were a new user.
After that class, and overnight, I can do a completely fresh install of powermessenger at the new location on the same basis, installing afresh by downloading from my Account.
I can then do basic testing on that fresh install.
Then if necessary, I can carry on testing on my main domain entirely for any lurking user errors
Please advise if I should proceed on that basis.
Then I can also take my time and eliminate all errors as might be caused by me rushing, and adding unnecessary difficulties for both of us.
We can then reconvene in the AM with anything further.
