I am upgrading my 1.3.8 to 1.5.1 to a totally different directory . I also copied the config files over to the new folders with the change in the directory names for the 'store' to 'shop' but still getting this error only during upgrade.

My original admin name was changed to 'blah', so when I re created the new files, I renamed the 'admin' to 'blah' in ' shop' but during the upgrade it is still looking for 'admin' instead of 'blah'

Can anyone please tell me why please?

Thank you
