Thank you for fixing issue #3, but 1 & 2 are still there in test site (test.sosailize.net and test.sosailize.net/administrator).
not fixed issue 1) no "infinite scrolling" although enabled
not fixed issue 2) no "show more" button or not working,
fixed issue 3) "order" not by last comment: now the comment "2 hours 37 minutes ago" is first and the one "8 minutes ago" is second.
It can be related by order by last comment, anyway we just released beta version 4.3, if you dont mind please you test it on your test site, i hope it will be fine there.
Yes it is related to "order by last comment".
When i disable "order by last comment" in all versions (4.2.5, 4.2.6, 4.3_beta_2) then the "infinite scrolling" works!
When i enable "order by last comment" in all versions (4.2.5, 4.2.6, 4.3_beta_2) then the "infinite scrolling" stops working!
So i could keep it disabled and use the latest versions but versions 4.2.6, 4.3_beta_2 have an issue (not 4.2.5) with "Top Members module for JomSocial" that already told you in another "help question" and don't want to use them in live site.
i installed jomsocial 4.3_RC1 on my test site (test.sosailize.net) and when enable "order by last comment" then the "infinite scrolling" is not working. It starts working when i disable "o.b.l.comment".
