[SOLVED] Global planning display issue

Hello ,
we were in version 9.0 we are actually in version 9.2.2 , in the global planning view we see only the tasks  we do not see tickets or any other element , this behavioue is the same since the last versions that we had. We never did any migaration to database or any thing else we only do updating to projeqtor regulary when a new version is published.
thank you for your help and assistance.

Any feedback please

In our case changing the database to utf8 helped (default was utf8mb4, which didn't work).

We changed changed the database configuration instead of implementing the workaround mentioned in following ticket
