OK. Now I can say – this is somewhat embarrassing. After checking that the database was installed correctly, I called Bluehost. The tech went to my site and didn’t see the error message. Turns out Firefox was defaulting to an old web address even though I had cleared out the cache. I deleted the old web address (shift + delete) and emptied the cache and everything is fine. Thanks everyone for your help.
I’m not sure if database is setup properly. I used Bluehost to setup WordPress on the server.
Thanks for the reply. Tried posting a test post, but I still get the same message.
