Try adding - in your .htaccess
max_input_vars = 3000
Seemed to cause my site to stop functioning when I added this in, not sure if I added it in the correct place though. Is there a particular place I'm supposed to add it?
If that doesn't work, try creating a php.ini in your root directory of your web server and put it in there.
There's already a php.ini file in my root directory, I tried adding max_input_vars = 3000 to it but it didn't seem to affect anything.
I contacted my host's support:

I just put that line in my htaccess?

Not php.ini?

FYI this isn't for wordpress, don't know if it'd be the same on both

I do apologize, as this would be Site Customization, this would technically be out of the scope of our support, but how was the site built, and I will look up some useful information for you.

ah, okay. I was using software called "Xenforo", I was receiving error messages with it. Their support told me edit the max_input_vars php setting, but I couldn't find this setting in my php.ini file where I expected it
10:14:43 AM
Me
It's set to 1,000 by default
10:15:53 AM
Jacob
Yes as default I believe this is the standard setting. Please allow me one moment to look up some information, thank you for your patience.

It isn't in the php settings listed as "cannot be changed" support.hostgator.com/articles/cpanel/php-settings-that-cannot-be-changed so I thought there'd be some way to change it

I do apologize this would generally be out of the scope of support, so I can not say if someone else will know this, but I can tell you that you should be able to make a php.ini file, and code it with a default php coding and add in this record.

It doesn't sound like it's prohibited from this conversation but he didn't really seem to know exactly how to edit it either.
