While this post is old, I came across this issue when using XAMPP and found the solution here: https://bbpress.org/forums/topic/error-are-you-sure-you-wanted-to-do-that-3/#post-142468. Once I updated my theme’s function.php file with the suggested method, all worked correctly for my local XAMPP website instance.

BTW, before adding the fix above, when attempting to create a topic or reply, I did not see any error message, in fact no message at all. The page simply reloaded and left the pending topic or reply text sitting inertly on the screen in front of me…
