It seems when a post (of a registered user; still under spam control) is in moderation, in the forum overview the last post is displayed as "By Anonymous, 50 years ago". Is this intended behavior?
Maybe it's related to the bugfix (one or two versions ago) to show the latest reply instead of the first post for a forum in the forum overview?
If this is not specific to your site, then it would be nice if you tell us what kind of php you use, what kind of mysql you use and anything non-standard you may have.
Also are you error free ? I mean is your debug.log emty ?
Also searching for what you say on google, i found only 4-5 sites.
@herwin Could the mysql version be a problem ?
Because i read here
https://wpforo.com/docs/root/wpforo-installation/server-requirements/
about mysql 5.6 or later. @robert could comment on this.
