Users cannot edit topic or post
Also please note, if a new topic or post become Unapproved the user will be restricted to edit/delete it. This is designed for antispam purposes. wpForo 1.2.0 comes with built-in Spam Control functions and it automatically set unapproved new users topics and posts if they are suspected as spam. Spam suspicion level can be managed in Dashboard > Forums > Tool admin page, and you can make it more smart by installing Akismet antisam plugin.
I know it's a free support, but if there was a way to have a premium support on that plugin, it would be great. I really need that stuff to work, as I use it in a course with almost 100 users now, and no one can edit his topic or post. So, if there is a package or something for a premium support, I take it. Thanks.
All those problems i'm reading just can't happen in a well working WP installation. They just can't.
Why don't you follow the standard WP debug procedure ?
Enable WP debug to a LOG, Disable for a while ALL plugins, switch to default WP theme. And see the results. Errors in debug.log maybe ... See if wpForo work ok without any plugin.
Also what webserver is this ? PHP version ?
( of cource all the above stand IF you have correctly set the permissions of access in wpForo setup)
Ok, I will see that with a dev, cause I don't know how to do that. (debug).
