HELP PLEASE NEW TO BBPRESS
It is most likely a cache issue on your end. Make sure you have WP-Super-Cache set up correctly and that the cache refreshes when a new post is published or updated.
Clear all cache files when a post or page is published or updated.
I saw this message on your forums page source code that is why I know you are using that specific plugin.
<!-- Dynamic page generated in 1.073 seconds. -->
<!-- Cached page generated by WP-Super-Cache on 2015-08-25 19:54:03 -->
<!-- super cache -->
Also do not post multiple topics of the same issue, just update your original topic.
Thanks for the reply Robkk I checked super cache for Clear all cache files when a post or page is published or updated and it was checked and i also tried to reset the super cache settings but still the problem occurred.
What troubleshooting did you already do? Did you already do the plugin and theme troubleshooting?

Also sometimes it may not necessarily be a caching plugin, it could also be other thing caching your site, like cloudflare, hosting server cache, something like that.
You can always test your sites theme/plugins on a test server.
