Need some help with changing cookie prefix in IPS 4.3.6

[beats23]

I follow the tutorial below, created a constants.php file, copy and paste the code from the tutorial to the constants.php file, place the constant.php file in the root IPS suit directory, clear IPS cashe, and browser cache and cookies.

The IPS suit cookie prefix is not changed and still the same ips4_

Any advice on how to fix this?

Thanks

Did your constants.php content start with <?php  ?

Hi, I have this in the constants file.

 

and I get his error page when I reload the page after placing the constants file in the root directory.

Ok adding <?php at the top in the constant file fix it. It works now. Thanks
