In test environment i tried to upgrade VM from version 3.0 to the new 3.3.
Components and plugins do not automatically recognize an existing update so I tried to do it manually. As I have customized some tags from label language menu, I want to keep those changes. I installed the new VM from Joomla extension manager but the result is that all the frontend tags and backend VM menu labels are displayed as the constant and not the values (eg _VEHICLE_MANAGER_LABEL_PRICE_TYPE: , _VEHICLE_MANAGER_LABEL_ISSUE_YEAR
In laguages shows English twice. I tried to fix it from my DB importing the old table in vehiclemanager_const_languages but nothing happened.
What's the best way to do the upgrade without losing the settings and language customizations?
Thanks!
