You can use the Duplicator plugin to create the staging site.

The issue with commenting might be related to the membership plugin you are using, since the admin is able to post comments. However, as I already mentioned, it is too difficult to perform proper testing on the live website. You can try deactivating the membership plugin and check if the issue still exists.

The developers will check your website soon. I'll update this topic once I get a response from them.

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

I'll discuss this question with developers. 

I ran a lengthy session with the Hostinger AI troubleshooter, Kodee. She had me use the browser's DevTools Network to see what was happening. Somehow, it is calling the request from my local server URL instead of my webpage. 

Rochelle — if Origin is missing and the initiator is just jquery.min.js, that usually means some inline script/plugin code is calling $.ajax("https://127.0.0.1/") (jQuery is only the transport, not the source).

Rochelle — that pins it to wpDiscuz’s JS bundle, so the 127.0.0.1 URL is being fed into wpDiscuz as its AJAX/API endpoint (it doesn’t originate from jQuery).

Next steps (one path at a time):

1. Find the localized wpDiscuz config on the page: View source → search for wpdiscuz / wpcd / ajaxurl / admin-ajax.php and paste the JS object near it (it should contain the URL wpDiscuz uses).
2. Clear all caches: purge LiteSpeed Cache + any minify/combination cache, then hard refresh (Ctrl/Cmd+Shift+R). Combined scripts can keep old endpoints.
3. If it still uses 127.0.0.1, the endpoint is being altered by a URL filter or config mismatch—most commonly:

• WP_HOME/WP_SITEURL in wp-config.php
• home/siteurl in wp_options
• a plugin filtering home_url()/site_url() (MU-plugins are prime suspects)

If you paste the wpDiscuz config object from page source, I’ll tell you exactly which WordPress value is wrong (and where to correct it).

I'm not sure exactly what she is asking for in step 1, and I was wondering if you or someone with more coding/development experience than I have (which is none) could help me figure out what the JS object is or how to find it? I have been reviewing my files and databases for any instances of 127.0.0.1 and haven't found anything so far that would be misrouting the URL to the local host instead of my website. Any light you can shed on this issue is greatly appreciated! Including my DevTools screenshot for you.
