The latest version of Contao 4.4 is currently 4.4.40.

Did you try clearing the cache var/cache?

[essecosi]

Yes I'm :-(

What is that supposed to mean?

I would try the following:

• Rename composer.lock to composer.lock.bak
• Rename the vendor/ folder to vendor_bak/
• Purge the var/cache/prod/ cache directory
• Run the Contao Manager
• Mark all packages for update, confirm the selection and finally perform a complete Composer Update of all packages (make sure to use the Composer Resolver Cloud)

yes, much better, but seams like one of extension not compatible!

That's quite possible. What extensions have you installed? And how did you install them?

[essecosi]

installed with contao manager.
I need one "simple" booking form for education, but with calendar where you can see free and reserved termins!
