Running on Linux & when I put this line into my .htaccess file I get an internal server error; what is wrong with it?
php_value include_path ".:/usr/local/php5/lib/php/PEAR:/usr/share/pear:/home/username/public_html/includes:.."
Server was using suPHP as the handler & that handler doesn't support setting php values via the .htaccess file; they have to be set via the php.ini file.
