OK, after working with many folks on how to debug rootspersona, I have added a debug flag to the options menu in version 2.3.1. If you are having a problem, please:
1) check the debug box on the rootspersona options screen
2) execute the problematic code
3) send me the output from http://yoursite/wp-content/debug.log
4) you can uncheck the debug box if you wish
This will help immensely in me helping you.
