This error happens when you are running an external script like a .pl or .cgi type script and it has to call an external program to run it.

Check the firstl line of the script.  It will (should) be something like
#!/bin/perl

make sure you have perl installed.  Make sure the executable is in that place and can be run by the web user.

make sure the script file you are running has 'x' permision for the user the apache is running as (or the one that would run the script)

Thanks for the prompt response. I am afraid I have covered all the common screw ups (I have been know to make them quite often).  Everything you site has been checked and is ok.  The problem appears to be an area where the perl code is actually generating some javascript (not my script). The code appears to be attempting a windows.open on a simple text file (a log) as in ".....window.open("data/log.txt")..."  The log file in question exists has 777 permissions and is in the data sub directory which is immediately subordinate to the current working directory. When I can I will post some of the Apache log file entries

Thanks,

Pete

go into the subdirectory on the command line and run the file and see if you get any errors etc

is the error showed in apache log or from your browser?

So if you take out that javascript code, everything works right?

window.open("data/log.txt") ... where (url)/data/log.txt is accessible in browser?

If you're debugging javascript, I like Firefox Firebug extension, it has some useful tool to debug, like breakpoint ..etc.  https://addons.mozilla.org/en-US/firefox/addon/1843

Yea, a sample log and more detail of how the error happened would be good.
