I upgraded from 1.2.6 to 188.8.131.52 version of MRBS.
Apparently the migration was ok and I have all my data.
During migration my users (3, all of them being admins) were correctly "imported" with their correct "rights" as I can checked by using phmyadmin.
However, if I enter into MRBS as one of these admins and I want to see "Table of users" to modify something about them (for example their rights) or for adding other users, I see what I attach in the 2 images, ie the "Rights" (= Diritti) selection box does not show any number (0,1,2) even if it has 3 lines I can choose from, and also the 'rights' column apper empy for all the users.
No idea for this.
