This is my website for which I need some assistance.
The first page visitors see is an Age Verification Landing Page. Please see the attached files for reference on my code.
I am experiencing cache and re-direct issues across all browsers especially Internet Explorer, and Firefox. If a user imputs 1992-2012 (under 21 years old) they will be re-directed to vipunlisted.com/leave.php. However they wlll not be able to click the back button, if they do an error message appears.
Is there additional code I need to add in the php section that addresses the way different browsers read php?
