Conflict with Perfmatters (Performance Plugin)

Hello,

I’m trying to install Perfmatters to optimize and speed up a website, it works wonders and makes every site I’ve used it with incredibly fast but I’m running into an issue when I activate the plugin on a site using Ninja Forms.

When perfmatters is activated, all the Ninja Forms styles contained in files “st-label-positions.scss” and “st-defaults.scss” are removed, which makes all inputs and labels reset to a bare-bones style, hidden elements are displayed (instead of remaining hidden) and a huge white box shows up where the success message (after the form is submitted) should go.

The problem is I cannot find these two files (st-label-positions.scss and st-defaults.scss) anywhere on the plugin folder, they seem to be mapped from another css file.

Anyone know where they are getting loaded from? I’m assuming they are loaded externally somehow but I cannot tell how, and I’m wondering if it might be possible to setup a rule within the plugin to allow this to happen. Anyone have experience with perfmatters and making it work with ninja forms? Any advice is appreciated.
