I rather think it might... Read very carefully the section on "Options"
in the docs to see what the point of the "+" is.

Briefly, if you don't have a "+" options directives which apply to the
same directory are NOT combined - instead, the latest one is taken. If
there is "+", then the options are combined e.g.

Options ExecCGI
Options Indexes

means the directory only gets "Indexes" but not ExecCGI. However:

Options ExecCGI
Options +Indexes

means it gets both.

I suspect you have another Options directive at the same level which has
"-ExecCGI" so when it gets "Options +ExecCGI" applying to the same
directory, you get a conflict (it is not clear how the Options would be
resolved in this case). If you do "Options ExeCGI" (without the "+") the
second directive will override the first and the script will execute.

If you can't find the  "-ExecCGI", use the second method which leads to
the "premature end of script headers" - that proves that the program is
executing. To see what output is being produced, test the script through
the server from the command line. i.e.

$ telnet server-name 80
GET /~user/cgi-bin/hello.cgi HTTP/1.0

(followed by two returns)
and see what comes out.

Rgds,

Owen Boyle.
