  • From a quick Google search I think some plugin wasn’t copied correctly across, as admin_register_head() isn’t a native plugin.

    What I suggest you do is deactivate plugins, and then reactivate them one by one. When that error appears, that is the plugin that’s causing you an issue. Redownload it from the WordPress repository, and then activate it, and see if that fixes it.
