You appear to have some add-ons or modifications that are being applied to the forum_list template.
There's some odd things going on like duplicated Forum Statistics.
I suspect that an add-on or template modification is modifying the profile posts list in such a way that is hiding it, or removing it accidentally.
It might be worth disabling all other add-ons too, and trying it on the default XF style. If the default XF style is not available then you can create a new style in the Admin CP with no parent to recreate it.
I can only help you troubleshoot the issue if widget framework and other style customisations are not involved.
For support with Widget Framework, you would need to contact the author.
For help with displaying the New Profile Posts block while Widget Framework is disabled, you would need to confirm the issue with a default XF style and no other add-ons enabled. This will be the only way we can find out which is responsible.
