UPDATE: I took everything off … again only this time I uploaded the latest version of WordPress. It still doesn’t work but am getting blank pages; I can log in. The themes (classic and default) are still showing up blank.
I am working on a site for my son’s band; I load the sidebar widget got everything working. I went to the site today to just check on it and it took FOREVER to load and then the main content was gone and everything mess up. I deactivated the sidebar widget pluging and now everything works, reverting back to the regular sidebar. Now, I am using 2.1, a widget compatible theme etc. – it was working just fine. Any clues?
I found the solution: it had to do with creating the subdomain and trying to install to that instead of the folder.
