I edited the apache httpd.conf file recently for the mod_rewrite to work. I don\'t know if this problem originated from that or not, but i\'m getting this problem from that
I got this problem when insert wrong file address into .htaccess
.htaccess
php_value auto_prepend_file "/home/user/wrong/address/config.php"
So if you use auto_prepend_file check your file path. It called from .htaccess so PHP can't determine error file and line.
