[HELP] 403 Forbidden

[superso3]

I have a php file where the user has to enter a specific password and if it's correct, it lets them in. The thing is, it's a POST request and every time I visit the site with the POST I get a 403 Forbidden message. I'm not sure whether it's a mod security error because I'm not using VPN, proxy, etc.. It works fine when I go to the link without using the POST request though

Have you checked if the MySQL query used works in phpMyAdmin? Have you sanitised the POST params correctly?
