Http://www.myleague.com/euchre101/admin.html Edit User error

I am an admin within a gaming site. When I attempt to Edit User data on this particular site, I get an error. This does not happen when I use Windows Edge. I would prefer to use Brave if I could use this site as intended.
http://www.myleague.com/euchre101/admin.html is the site in question. Also, I can’t use the save password functions on any of the following sites:
