Please note that this issue is related with the use of a third party plugin, not with the use of your theme. As theme authors, the installation, setting or debugging of third party plugins isn’t part of the support we will provide.
To go further, we invite you to ask for more help from bbPress plugin authors and post your request on their support forums: bbPress support.
We remain available for all support requests related with the use of your theme.
