Wordpress HTaccess is leading to 500 internal error

Ok, so my htaccess code is jacked and leading to a 500 internal error at addison-homes.com and I don’t know how to fix it…

AddHandler php-legacy .php

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

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

# END WordPress

php_value upload_max_filesize 128M
php_value post_max_size 128M
php_value memory_limit 128M

# BEGIN (mt) controlled settings
AddHandler php-stable .php
# END (mt) controlled settings

What is making it go awry?

I’m pretty sure it isn’t the Wordpress code causing the problem. Put a # sign in front of each line outside the Wordpress htaccess directives and see what happens. Then uncomment each line until you find the line causing the problem. Are you on shared hosting? Those PHP directives you have in your .htaccess usually don’t work on shared hosting. They go in php.ini files. I cannot say anything about your host-specific directives unless they are causing a conflict.
