I am trying to upgrade my Opencart from v2 to v3. I uploaded the v3 files and i am at the install page which says upgrade step 1 of 2.

Any ideas ?
As for the undefined error, it may possibly be caused by the install/model/upgrade folder where one of the PHP files contains:
By restoring backups without any extensions install and by following this FAQ afterwards: viewtopic.php?f=176&t=200804#p730051 . Everything should run smoothly.
