Hi, I installed WordPress a couple of days ago and have been strugglign with these problems ever since.
To start I will say that I have scoured these forums, done numerous google searches and have tried every solution I have found to no avail.
I have edited my .htaccess, httpd.conf and vhost.conf, enabled AllowOverride, tried to disable mod_security (couldn't find it in my httpd.conf), created a .htaccess for the wp-admin folder and all that stuff.
When I try to change my permalinks to anything but the default setting I get a HTTP 400 Bad Request error.
When I try to edit the style.css through the Editor I get a 500 Internal server error. However when I try to edit any of the .php files through the editor I get a 501 Method not implemented/505 version not supported error.
When I try to upload a media file I get a Bad request error.
I'm trying to run wordpress on an Apache 2.2.0 with PHP 5.1.6 and using Plesk as my server admin software.
I'm at my wits end. Please advise.
