IT WORKED! Thank you kind sir
I installed a new theme (not hueman) and same issue – so I think it must be a BBpress issue and not the theme :/
Note – it only breaks when someone is logged in. When someone is logged in, it kicks back a 500 internal server error on Posts (sorry not pages)
Seems to have fixed itself once I updated BBPress – nevermind!
ALSO is it possible to have something come up where when someone attempts to redeem an achievement but they are not logged in – to let them know in order to redeem achievements they have to login to wordpress?
