Forums Error: There are no posts for this topic.

Hi Folks,

When posting a new topic on the forums, the topic is created and appears on the forum however all that's displayed is the following message:

There are no posts for this topic.

The forums were working perfectly on my local XAMPP test environment.

I have tried the following fixes with no luck:

- Un-installing all plug-ins
- Re-installing the forums
- Disabling and then re-enabling 'discussion' on groups

Although I don't think it's related to the posting bug, the following error is shown at the bottom of the page but only when the user is logged in.

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'bp_forum_extras_index_screen' not found or invalid function name in /sharedstorage/sites/ on line 395

BP 1.2.6

Any help would be hugely appreciated.
