No more invoice after upgrade to 3.9.2

Using my Dolibarr
1

Hi,

I’ve filed this as a bug report there, but I haven’t received any feedback in a while and I was suggested to post on the forum as well:
https://github.com/Dolibarr/dolibarr/issues/5636

Long story short: after an upgrade from 3.6.2 to 3.9.2, I can’t create any draft invoices since after the form has been filled out, clicking the “Create draft” button leads to an empty page. A log excerpt is also available here:
https://github.com/Dolibarr/dolibarr/files/491302/dolibarr.txt

I’m not sure whether something might have gone wrong with the upgrade, and I’m not sure how to gather more information to figure out what the problem is.

Any help is welcome.

Cheers,
Cyril.

Hi,
Do you upgrade from 3.6.2 to 3.9.2 directely or do you upgrade gradually updating each step between 3.6.2 to 3.9.2 ?
Each step is necessary.
