As you can see into https://fr.wikiversity.org/wiki/Mod%C3%A8le:JackPotte/test, the behavior of the BASEPAGENAME and SUBPAGENAME magic words for this particular wiki in this particular namespace is different than all the others (eg: https://fr.wikiversity.org/wiki/Utilisateur:JackPotte/test).
Line 7 to 8 it should display "JackPotte", and 9 to 10 "test".
