Considering that PHP is up to v.8, you are going to have to upgrade at some point.

If you are using cpanel and a PHP upgrade breaks your site, you can always put PHP back to the previous version and they should work again. I’ve done this successfully on more than one occasion.

I've done the same. I had some php scripts that weren't compatible with php 7. I put off updating the scripts for two years. I finally sat down and picked my way through the errors to get them to work. These scripts were all custom one off scripts wrote several years ago. I've had no issues running Form Builder forms on php 7.

Wow what an interesting tool! I will definitely be leveraging this tool on my current and future builds. It seems like a lot of the issues with SD5 css files as far as performance goes. How on earth do i fix that?
