403 Error Access Denied, index.php root file only

Ok, so I successfully installed WordPress on a Apache server, and was immediately met with a 403/ACCESS DENIED error trying to sign in.

All of my file permissions are set to 775.

What’s even more odd is I can log into the wp-admin/index.php file just fine. I can access a .txt file, or .html in the root directory just fine, I can also access any image in any directory just fine.

I just simply can’t run my index PHP files in my root directory, or my wp-content/theme/nameoftheme/it’s index.php file. The root php files give me a 403/ACCESS DENIED error, and my theme/index.php file gives me a error string, failure to call function, etc.

I can however, run wp-login.php in my root directory, so it’s just the index.php file…

My .htaccess file looks as such :

# BEGIN WordPress

AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

# END WordPress

Please help, I’m at my wits end….
