Open edX - Login/Register submit button disabled after the first fail attempt


The default login/registration form of Open edX has a bug that will disable the submit button after the first fail attempt and seem like no one want to fix it. Fortunately, you can use the combined login/registration form which does not have that bug. You enable it by add this under the FEATURES list inside /edx/app/edxapp/lms.env.json:

"ENABLE_COMBINED_LOGIN_REGISTRATION": true

Then restart your apps and enjoy:

$ /edx/bin/supervisorctl restart all
