Help with Icyclub plugin – YoastSEO

Hello,
first of all, sorry for my English. I’m not a developer nor an expert, so I’ll try to explain as best as I can. I installed Icyclub plugin on theme Agencyup, in order to get a specific homepage template. I installed YoastSEO plugin too, and it doesn’t let me update the homepage after I modify YoastSeo options (this problem never occurs on other pages). I searched online and found out I should add the_content function into the page template’s code (how?!), or simply switch to another theme (which I really would not.). I really need to be able to update this homepage. I can’t modify it in any way. For example, if I try to modify it via Elementor, I get this message: “Sorry, the content area was not found in your page. You must call the_content function in the current template, in order for Elementor to work on this page.”
Please please please help me, I’m desperate
