Fresh/New install - Error: unable to initialise theme

I followed the instructions in the manual, Installing phpList manually, and after putting in the DB info, I went to the /lists/admin URL and got “Error: unable to initialise theme”. I assume this is phpList telling me this. I’m not sure what to do from here. Is this a bug of some sort or did I miss something critical in the installation?

@Digitalman You might not have copied the files correctly. The message seems to mean that this file does not exist

lists/admin/ui/phplist-ui-bootlist/pagetop.php

Bingo! Apparently, some folders and files did not get copied over as expected. UG! Hosting site has a nice file manager, but it fails something terrible at uploads. Going to zip up /lists and unzip on the site instead, that’ll make sure it gets everything. Thanks for the help!
