In a site:
first I upgrade comjaextmanager to 2.6.4 with success
then I upgrade T3 Framework and I have 500 - Internal Server Error
In an other site:
first I upgrade T3 Framework with success
then I upgrade comjaextmanager with success
So I find out a conflict upgrading to comjaextmanager 2.6.4 (see screenshot) that cause 500 - Internal Server Error when you upgrade other extensions. Now I'm not able to rollback.
Can you please help me? Thanks!
