Content Area not found!

Hello,

I am using Elementor Pro and the Elementor Hello Theme. Both work great, and I would really like to keep them.
However, I just installed the Custom Skin plugin, and I cannot create any loops, as the Content Area for the current template needs to be called.
I have had this issue before, but I was able to solve it by adding the function to the pertinent file. Not this time.

I tried deactivating all the plugins and activating them one by one. Ele Custom Skin was the one triggering the issue (or at least so it appears, since I can’t create loops with it deactivated anyway).
When I change the Theme, the problem disappears. However! I do not wish to change the Theme, as I need the blankness of the Hello Theme.

Is there anything I can do to fix it?
