Fatal error with switching themes in vanilla 1.3.6

I wanted to see what the Green theme looked like, and when I switched the theme on the main page from the sidebar, I got this error. I tried looking for the undefined function in the rest of the code with my editor, and it does seem to not exist.

Nevermind, it was because I assigned it to a usergroup in the admin panel. I reset it back to zero, but this means there is a conflict between the ACP and the basic site in how to switch themes using user groups.
