I'm trying to update Freeform (free version) from 3.1.2 to 4.2.2
NOTE: I recently updated EE from v2.5.3 to v2.9.3
After I upload the new folders to the system and themes directories, and go to:
Admin > Modules > Run Module Updates
I get the following error:
A Database Error Occurred Error Number: 1054
Unknown column 'settings' in 'field list'
Line Number: 471
I've tried to revert back, by replacing the folders in system and themes with the old version and, then I get this error in:
Admin > Modules > Freeform:
A PHP Error was encountered
Message: Creating default object from empty value
Line Number: 1333
Fatal error: Call to undefined method Cp::set_variable() in /admin/expressionengine/third_party/freeform/addon_builder/addon_builder.php on line 1389
And now I'm stuck...
