My project disappear

Hello everybody !

I’ve a little problem with gant chart. I use this chart for my work schedule.I work fine but some days I open my gantt, and I see that some projects have disappeared (but related taks are still there).

For exemple this morning i’ve this . While normally i’v many projects like this (this is a montage) : .

I check in database, the others projects that disappear are in the database but no longer appear. What is this bueug ?

Nb: sorry for my little english …

Ahah I find the solution …

My project date were less than the “gantt.config.start_date” that’s why he did not appear on the chart …

Thank you anyway !
