Hi,

Even though the General settings menu under the Settings menu is not visible there is no issues. You can change the Users group and settings from the following menus by keeping the developer mode activated,

1. Settings -> Users & Companies -> Users

2. Settings -> Users & Companies -> Groups

If you are clicking the Users menu, open the corresponding users form and choose the group settings under the Administration and save it.

if you are clicking the Groups menu, search for the group named Settings ( Administration/Settings), and open it and add the corresponding user to this group by clicking on the Add a line in the Users page.

Thanks

Good solution Ramzi. I was writing a ticket for support, but tried creating an Admin user, give my user the Setting Rights back, delete the new Admin user. 

Thanks
