While working with Big Business (for J4) I noticed 2 small errors that need to be fixed.
There's an erroneous line of code is creating a div that you can't get rid of w/o editing index.php
it's <div id="s5_pricing_bottom"> on line 424. need to remove that and one of the latter </div> to correct.For whatever reason, the custom BG for bottom row 3 renders with a space between the # and the color code you have selected, making the template not render correctly.
In that image you can see the template settings are set on the left, and over on the far right, you can see the code rendering w/ a space between the # and the number.
