We discover a bug when we use uppercase text in custom profile field.
Here are some information to view this bug.
- Go to "user profile fields" page
- Create a new profile field (for example text)
- Add a short name and use at least one uppercase in the text (see screenshot)
- Add name and save
- Go to "Notifications" page. You are redirected and blocked on admin/upgradesettings.php page with authentification plugin option. (see screenshot)
If you delete uppercase in the short name of the profile field, "Notifications" page works again.
(PS : test with php 7.2 and mysql 5.7)
