I think it has something todo with the spam protection because the first post works and when the user and its previous posts are after the second or third marked as "moderated" this error message comes. If I klick on the browser "back" then it also shows me that the current and previous posts are moderated and need approval by admin. Hope this helps to verify the error... Many thanks
Usually the "Warning: Cannot modify header information - headers already sent by" COULD be the result of a modified php file (by hand) and inserting some White Space.
Have you modified by hand anything in WP or wpForo PHP files ?

Have you modified by hand anything in WP or wpForo PHP files ?
No I have not modified anything. Neither on the wordpress install nor on the forum software. I have a managed wordpress server and therefore not even the possibility to modify it.
Any caching ? Plugin or else ?
Yes -> Yoast SEO and Akismet
Neither Yoast or Akismet is a caching plugin.
Also enable DEBUG.LOG and check.
This is something strange, it looks like the wpforo_subscriptios table is damaged in your database or subscribers where not users. We're going to adapt wpForo core for such case in next version release. But for now please do this small change in wpForo files. Open /wp-content/plugins/wpforo/wpf-includes/wpf-hooks.php file using cPangel > File Manager or through FTP client.
Find this line:
if( isset($topic['status']) && $topic['status'] == 1 ){
Change to this:
if( isset($topic['status']) && $topic['status'] == 1 && isset($subscriber['userid']) ){
Please Note: there are two lines with this code, you can change both (line 1365, line 1280)
