you need to add "import html" under "import cgi" and then change "cgi.escape" to "html.escape"

[mbn-code]

when i try to edit that i just get permission denied

try doing the same thing with sudo command:
navigate to: root/usr/share/set/src/webattack/harvester
and run the following command:

$ sudo nano harvester.py

use ctrl+w to find cgi.escape and change it to html.escape, i guess u are not familier with linux so i may tell you that after searching the word will not be highlighted but the curser will go to the word... search on the screen for the cursor after you hit enter to search

then press ctrl+o to write out(save)
then ztrl+x to exit
