Hi Deano,
Thanks for taking the time to look into this for me and send a reply. You found something obvious that I overlooked completely!
I've tried as you suggested, registering the "conventional" way via "Join now", and it worked. I got my confirmation email, and was able to log in after this.
I tried a few of the site functions- wall comment, etc and all seemed good. however, when I tried to change / add an Avatar image from my computer, the site logged me out afterward, and all attempts to log in again were met with "Error! Your username or password was incorrect. Please Try again."
Tried this twice- same result.
I tried logging in with an old member name, that I created earlier when the site was working OK. When I changed the avatar, I got the same result as above. The site logged me out, and unable to log back in.
I created yet another new member, but didn't upload a photo as part of the registration, and didn't change the avatar. This account remains functional.
Tried again- created another new member, with no photo upload. The account worked fine until I tried changing to one of the avatars from the library instead of uploading one. This caused the predicted logout without any way to reconnect.
I'm completely baffled here. Can you - or anyone else - help me to resolve this and get my site working smoothly again?
Much obliged to any and all who can (or try to) help me out with this!
