AJAX Infinity Plugin

I have already checked all the settings and reviewed possible errors, but I cannot identify the cause of the issue. Additionally, I could not find any instructions for setting up this plugin on your website. I posted a message on the forum, but my post has not appeared, and I have not received a response for two days.

I would really appreciate technical support for the product I purchased from you.

Good afternoon!
It has been more than two weeks. I have sent all the requested information, but I still haven't received any technical support. The plugin is not working.
