Could you please send the admin login details of your staging website to infogvectors.com email address? I'll ask the developers to check the issue for you. 

Host: Siteground business

Theme: Genesis Framework + Child Theme - latest versions

WP Version: 5.4.2

Environment: Staging 

wpDiscuz Plugin Version: 7.0.3

Primary wpDiscuz Settings: "Initiate AJAX loading after page," "Lazy Load comments on scrolling"

Native WP Discussion Settings: Unchecked - Break comments into pages of '10' top-level comments

Pretext:

Thanks in advance for your team's input toward the WP community.

Moving on, I have read topics ini this forum raising the issue of caching conflicts and noted support's emphasis on clearing all cache.

Issue:

Conflict with Siteground's SG Optimizer caching plugin. 

Output:

Comments loop—infinitely repeat themselves—with output dependent on the native WP discussion settings indicated above. If top-level comments are set to '10', then 10 comments will be displayed before looping. If top-level comments are set to '2', then 2 will be displayed before looping commences. 

Attempted Solutions:

1. Disable plugins independently to discover conflict. Isolated SG Optimizer

2. Purge all Siteground caching

3. Purge browser caching

4. Reload

Note:

wpDiscuz does execute as documented when SG Optimizer is disabled.

Additional trouble-shooting thoughts?

wpDiscuz v7+ offers a robust commenting solution, and we would like to incorporate it in the client's site. Any insight would be appreciated.
