Comment Bug
This is what happens when installing a beta version of Pivot or any software for that matter. Somehow the new version inserts some Javascript to check the comment form before submitting. If it's not correct the submit button is 'grayed out'. But the thing is, it doesn't work!
So for now the commenting is disabled until the issue gets resolved. Thank you for your patience, now hope mine is long enough
Update: If you're experiencing the same problems, a temporary fix is to disable the Hashcash functionality. Commenting is enabled again, for now...
