Re: [ploticus] CGI ISSUE
Be sure you're using ploticus version 2.04 which fixes some CGI-related
Try using the -debug argument, which should produce diagnostic files on
Your web server should be setting environment variables QUERY_STRING and
SCRIPT_FILENAME and making them available to the CGI process that is
invoked. I believe this is W3 standard behavior.
If you do other CGI programming (ie perl or whatever), see if you can
arrange to display the CGI environment. For example, on unix you could
issue a "set" command.
If none of this works send me the following:
The contents of the /tmp/plcgi* files after trying -debug
Your os environment
Your web server brand and version
A copy of your config file
A simple HTML file that has your <img> tag in it
