I also have WordPress installed and I get "You don't have permission to access /wp-admin on this server" as well. This started about about 12:00-1:00am and I haven't been able to resolve the issue! The weird thing is that I haven't changed ANYTHING, why would this start happening? The website is on a shared linux server through ARVIXE Web Hosting. I checked the error logs and I see: [Sat Apr 02 09:55:26 2011] [error] [client XX.XXX.XXX.202] client denied by server configuration: /home/username/public_html/domain.com/403.shtml Code (markup): Also, I run vBulletin on a subdomain forum.domain.com and I can access that fine. Any help would be greatly appreciated. I'm missing out on a lot of traffic!
Figured out the problem. the line "deny from all" was added to the .htaccess and was last edited April 1st at 23:37 Could this have happened on the server administrators end? Or could someone have accessed the file from the outside compromising the website?
Make sure your .htaccess isn't writable. If it is chmod to 644 then noone but an administrator should be able to write/edit it.
