pros and cons

Hi there,

You have many console errors currently.

I would recommend trying #1 here first:
https://docs.generatepress.com/article/debugging-tips/

including better font awesome?

No you can keep that one and GP Premium on.

is the site still getting console errors?

this is the post i used to get the code and css.

Try editing your CSS to this:

.comparison-column.pro li:before {
    content: '\f00c';
    color: green;
    margin-right: 10px;
    font-family: "FontAwesome";
}

Awesome that worked for pro, so now i assume i just do the same for con

Yes :)
