Re: PHP 5 and “500 Internal Server Error”
Can you look at any logs to see why the 500 error is occuring? Sounds like the web server does not allow the directives you’re trying to use in .htaccess.
BTW, I use
AddType application/x-httpd-php5 .php on almost every install without a problem. Maybe the server just doesn’t support it. Does your host have instructions for enabling PHP5 for your webspace?
