All right thanks, this module is indeed usefull and i'm pleased it exists even with my difficulties. Good energy for the analysis.

Hi, many of the pb have disappeared with the WE...
I won't be surprised if a change in configuration, rights...needs a bit of time.

I add a screenshot of the leaves system habilitation. There is only one column for calendar (which should explain my imposibility to change anything on the calendar when I want to create a leave. Is this du to another habilitation or configuration ?

Thank you.
