Hello I installed the role UI plugin but the button to save the changes does not appear I do not know why if someone can help me.

thank you in advance

RoleUI plugin has been written for Elgg 2. If you are trying to use it on Elgg 3 or Elgg 4 it probably won't work anymore.

I'am trying to use it on Elgg 2.3.0 the version same version with Role UI..... but i don't why the button save disappears

Where did you download this plugin from? Provide a link please.

I just installed this plugin and couldn't find any errors.

All 'Save' buttons are there:

/admin/roles/create

/admin/roles/permissions?role=visitor

/admin/roles/permissions?role=default

/admin/roles/permissions?role=admin

Elgg 2.3.17

Try to run 'Flush the caches' and check again

By the way, there're Roles and Roles UI for Elgg 3 also:
