Hope all is well.
Just a follow up on you issue regarding the slider, were you able to resolve this? Seems like the slider is back on. 🙂
In regards to the 4 boxes, please see our guide on how you can make the changes/ customize: https://theme4press.com/docs/setting-up-the-home-page/. On the guide, navigate to “Boxes on Homepage”.
I hope this information helps.
