[OzzModz] Find Reactions

[OzzModz] Find Reactions [Paid] 2.1.1

No permission to buy ($12.00)
Hi! I have a dumb question. I've purchased the add-on, installed it, and given the admin group permission to use it. I must be missing something. Where is the search accessed?
Nevermind, I figured it out. I did encounter an issue. A search of reactions given to a specific member between certain dates is successful. If the results span multiple pages, pagination shows at the bottom with a Next button. However, page numbers and/or Next both result in an error. Any words of wisdom?? Thanks!

There is nothing in the server error log, it simply says Oops! We ran into some problems.

The requested page could not be found.

This is on a php 8.1 install, if that matters.
