New comments no longer appear on the front page

Okay, maybe the problem is that I transposed my numbers and you took that to mean I was three versions out of date. I'm sorry about that.

For clarity, again, the site I am testing on IS on 4.1.4 and the issue still exists with no cache and with no other plugins and with the site running the stock WP theme.

I'm sorry but I have no clue what's wrong with your website and comments. The only way to be able check it and fix is having admin access. Please send admin login details to support[at]gvectors.com email address. We'll login and check it within 1-2 days.

Ok, we found the problem. It only appears when the default comment pagination is turned on [1][2][3]... I recommend change this to standard wpDiscuz pagination with [Load More] button till new version release. Next wpDiscuz version will come with fixed core. To change the default pagination to [Load More] button you should uncheck the "Break comments into pages..." checkbox in Dashboard > Settings > Discussions admin page.

"load more" is not an option for us - reverts to an SEO disaster with the multi-page comment, anchors, etc. so we will wait for the new release/fix, thank you.
