I have recently downloaded Experience and installed it in one of our testsites. Everything perfect so far. There is just a little issue, where I need some advise atm: how to align the labels and the input elements vertically (screenshot).
I ve tried different settings and either it was partially done on the left side, or totally chaotic.
You may need to look at your theme elements using any developer tool , it will show you if the formatting on your site page is inherited and see if you need to add css. You may alos try different plugin styles, you do not mention which one you are using, P.S. SLP version 4.7.8 is out
