Found the problem in the ubbt.inc.php file.
Have a question about the instructions for changing the editdisplay.php file. The actual select statement in the original file has the following statement with the U_Username, U-Bio at the beginning:
SELECT U_Username,U_Bio,U_Sort,U_Display,U_View,U_PostsPer,U_TextCols,U_TextRows,U_StyleSheet,U_Preview,U_PictureView,U_PicturePosts,U_Language,U_FlatPosts,U_TimeOffset,U_FrontPage,U_ActiveThread,U_StartPage,U_ShowSigs
The the change to be made listed in the instructions does not have those 2 variables:
### Change this:
SELECT U_Sort,U_Display,U_View,U_PostsPer,U_TextCols,U_TextRows,U_StyleSheet,U_Preview,U_PictureView,U_PicturePosts,U_Language,U_FlatPosts,U_TimeOffset,U_FrontPage,U_ActiveThread,U_StartPage,U_ShowSigs
### to this:
SELECT U_Sort,U_Display,U_View,U_PostsPer,U_TextCols,U_TextRows,U_StyleSheet,U_Preview,U_PictureView,U_PicturePosts,U_Language,U_FlatPosts,U_TimeOffset,U_FrontPage,U_ActiveThread,U_StartPage,U_ShowSigs,U_SideBar
Also the list statment does not have the $CheckUser and $Bio variables:
### Change this:
list($Sort,$Display,$View,$PostsPer,$TextCols,$TextRows,$StyleSheet,$Preview,$PictureView,$PicturePost,$chosenlanguage,$FlatPosts,$TimeOffset,$FrontPage,$activethreads,$startpage,$sigview) = $dbh -> fetch_array($sth);
### to this:
list($Sort,$Display,$View,$PostsPer,$TextCols,$TextRows,$StyleSheet,$Preview,$PictureView,$PicturePost,$chosenlanguage,$FlatPosts,$TimeOffset,$FrontPage,$activethreads,$startpage,$sigview,$showsidebar) = $dbh -> fetch_array($sth);
Should the first 2 variables be used after the change?
