Error after migrating site with Installer

OK, this maybe outside of the range of support you are able to provide, but I just attempted to migrate my site from a local (MAMP) dev to the production URL using the Duplicator plugin.

Everything seemed to go ok through the install process, but now if I try to go to the site I get an error msg "Fatal error: Call to undefined function wp() in /home/wodwya/ on line 14" I cant even get into the WP admin site to edit any configurations.

Any help is greatly appreciated!
