@jfinstrom - i had this same problem but i had two errors showing.
.htaccess files are disabled on this webserver. Please enable them
and
.htaccess files are disable on this webserver. Please enable them
Following the instructions on: http://wiki.freepbx.org/display/F2/Webserver+Overrides (thanks by the way) worked to fix the misspelled error but (.htaccess files are disable on this webserver. Please enable them) is still showing on my security warnings page. inside of the conf file is there anywhere else i need to enable overrides or even another conf file ?
