[phpesp-general] error on espresponse.inc on line 156

[Chuck S. <ch...@te...>]

Anyone have an idea on this?
It seems to happen when I have a !other field in a multicheckbox question.

Fatal error: [] operator not supported for strings in
/usr/local/lib/php/contrib/phpESP/admin/include/lib/espresponse.inc on line
156
