Jappix not working after update to YunoHost 2.4

I have upgraded the Yunohost version to 2.4.
After upgrade Jappix is giving Error:Service unavailable

The jappix after updating gives error in mysql.

Even noticed that Agendav is not showing any calendar activity or event.

After upgrade to 2.4, my jappix is working fine but I never used it before…
I got the same warning about the Table collected_contacts but I “guess” that it is used by roundcube and not jappix.

About Agendav, I have the same issue. Maybe, it is better to create a dedicated post about it ?
I checked the logs about agendav but didn’t find anything interesting :

Agendav is not showing events but I can see them on my phone. i misunderstood kanku post
I can create new events in Agendav and they will appear later on my phone.

I followed the Agendav documentation for troubleshooting but there was no more interesting logs than posted previously
