Ok. So I’ve upgraded to WordPress 5.5. Solved some of the problems.
Still thE BIG BIG issue is that my commentaries have disappeared. It show that I have the commentaries, I can see them in the admin panel, but not on the page. After the update I tried to make a comment. And the same… it doesn’t show it but it’s counting it.
Probably a Theme related issue, and as I made the theme (in my limited way), can I ask what is the a small change to the comment system in 5.5, maybe I can fix it? Thank you. Most appreciate it.
