okay:
1) I created brand new database on the server
2) uploaded the files from pbpbb 3.2.2 to the server
3) went through Install per normal
4) after install, the board was working fine and was able to access the board as a user and as an admin
5) then imported the old database
6) went through the Install again
7) there was two options, "Update" and "Convert". I chose "Update", which offered "update the database only", which I did
8) tried to login to the new board and got this (which is what I got at the beginning of this journey

This keeps referring to a style call "all", that apparently is installed with the 3.2.2 installation, since I did not put it there. Style has nothing in it except one folder, "template", which as one file, "feed.xml.twig"
The board is at new address:
http://saintpiocenter.org/Academy/campus/
How is this fixed?
