Not sure if there is a solution posted here as I did a search and could not find it.
I faced the error 403 problem when I try to login into my WP admin. Did a search at the forum and WIKI but found no solution.
Look around my server and found the problem: .htaccess file located in my root directory: http://soulworks.danielck.net
The default file pointed is index.htm
I deleted the .htaccess and I am able to access the admin interface.
- hope this helps! :)
