Hi David,
Thank you for bringing this issue to our attention.
Please note that this issue is related with the use of BP Global Search 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 the plugin authors and post your request on their support forums:
wordpress.org/support/plugin/buddypress-global-search
We remain available for all support requests related with the use of your theme.
Regards,
