DW Reactions Pro breaks my theme

Hello Sir,
DW Reactions worked fine, but DW Reactions Pro breaks my theme in several ways. I just bought and added it. Almost as if it is loading every hidden element of my theme at once, and loading pages within pages when you click links. Very weird.
# How the site looks before and after:
1. Here is the site working as normal, before installing DW Reactions Pro: https://mediatricks.org/wp-content/uploads/2021/12/working.png
2. Here is after installing the plugin, with broken header and footer: https://mediatricks.org/wp-content/uploads/2021/12/broken.png
3. Weirdly, here is what happens when you click a link on a post to go to another post: https://mediatricks.org/wp-content/uploads/2021/12/broken2.png

(As you see, it doesn’t go to the new URL, it loads the content beneath in a weird way.
# How I tried to fix it:
a). I have disabled all my other plugins one by one to see if it was a plugin conflict, and it is definitely DW Reactions causing the problem.
b). I also uploaded the plugin through my ftp and also through wordpress itself, and it caused the same problem both times.
c). The problem happens on all 3 reaction styles, and no matter what settings you use to embed the reactions unit.
# Is this an issue you know how to solve?
Many thanks
P.S. DW Reactions free version did not cause these issues.
