Of course, forgive me if you do not understand me is that I use the translator..
I have users in the active directory that does not let me select them.
when I look for them if they appear, but when I want to select them to create a ticket, for example, I do not select them.
I found the error and it is because those users have some accent in their name or surname.
that's why it does not work with users who have accents.
if the user does not have an accent, the plugin works correctly.
