This article applies to shared hosting plans our https://cp.blacknighthosting.com platform only. If you are on our older cp.blacknight.com platform please email firstname.lastname@example.org if you need some php settings changed. If you want to change the PHP version itself on this platform please see here:
Log in to your https://cp.blacknighthosting.com account and go to:
Sevices > My Services > Click on your Plesk plan (not on the domain name itself) > PHP Settings
1. Sevices > My Services > Click on your cPanel\Wordpress plan (not on the domain name itself) > cPanel
2. In the cPanel interface click on MultiPHP INI Editor > pick the domain you want to edit from the drop down (while you can try set the limits as high as you like here, they will not actually be any higher than the server limits)
If you do not know what a setting means, and your website developer or website application isn't asking you to change it, then you should not change that setting.
You might need to look at a cloud VM plan or dedicated server if you need to set a limit that isn't changeable here, or if you need a higher limit than you can set here.
