I am not a programmer but I do have ample computer experience. I cannot login as admin to my WP blog on my website for three months now, and frankly, it's been nothing but trouble since day 1. I do not have the time or experience with removing and renaming php files, nor should I have to at a user level. I don't understand why WordPress doesn't make their product more user-friendly for your average writer who should not have to have a double career as a programmer. My webmaster is also stumped, and my hosting company says it's not their problem.
I'm just very, very disappointed and will probably just remove everything and move to another product.
Sorry guys but I'm beyond frustrated.
