Here is web.com’s responce to my problem:
Thank you for contacting Technical Support regarding not being able to login to the admin control panel of your WordPress account.
We apologize for any inconvenience this may have caused you. The default page for your the worpress admin control panel is the index.php file. It is not being recognized by the system as the home page that’s why you are getting a 403 error when you try to login. For this matter, you would have to set index.php as the default page for wp-admin folder through the IIS manager.
