I have tried to deactivate all plugins and the theme. Nothing helps.
When I am logged in as myself and I reply on a forum, I move the cursor into the textbox and click, that sort of resets the page and I get a new url with #post-number. Then I can type in the box and it works every time.
When I login as the user (and there are a few of them having this issue), when I click the cursor into the box nothing happens. no page load, no #post-number appears. Then when I hit submit the page just goes back to the main forum page.
