Error message?

Fatal error: Call to undefined method BxPagesModule::isAllowedReadForum() in /inc/classes/BxDolTwigModule.phpon line 870

i clicked on the forum link and got this error... Reason might be? 

1.  you might be missing that action in the database.

2. the method might really be missing from the pages module.

3. you might need to add a folder in modules/boonex/forum/integrations for the pages module ???

4. maybe none of the above.

maybe it is a read/write for (FORUM) check for the member that can't be checked and created the error.
