pfSense

Created a shaper on interface, did not apply, set bandwidth to "100%", clicked apply
Cannot open firewall_shaper.php anymore, just shows error below on fullscreen.
Revert shaper configuration via Backup & Restore solved it.

Cause seemed to be the percentage on the shaper. Perhaps it doesn't support it.
Config below.

Error:
