Pothi - you are right, there are two installations. One at the root, one in a subfolder. I did that when I was first installing wordpress, couple years ago. I have been ignoring the one that is in the subfolder all this time - only using the one at root. But since I updated the database configuration this morning, every time I try to log in to admin, it sends me to the wordpress installation in the subfolder - the one I've been ignoring. So I deleted it from server (after a lot of consternation). Now, when I log in to admin, It still wants to go to the one in subfolder, even though it isn't there anymore. I can't seem to force it to find the one at root.
songdogtech - I tried what you suggested, although it doesn't seem to be affecting anything, probably because of what I told Pothi, above.
Do i need to change something else somewhere?
