Help! I upgraded to WordPress 1.5. Everything worked fine until I tried to set up my own theme. Now I'm getting a 403 Forbidden message. I've deleted the theme that I tried to use before the 403 Forbidden message would occur hoping that I could at least access the blog and then use a test page to figure out the problem. No such luck. I still get the forbidden message. I have tried deleting the .htaccess file but it doesn't seem to want to delete.
Can anyone help me?
