OK I'm really not as technical as most people in here so I won't be able to answer any questions about this.
The thread did lead us to solving this problem and I felt compelled to post what we did because it's super simple to copy exactly what we did.
After reading this post I did not want to screw around with a file that was on my system but I didn't mind changing any files that came with eTicket. I can always upload an original copy.
I opened the pipe.php file in WordPad and added one line to the top of the file after the php code started.
This is what I added: "chdir(dirname(__FILE__));"
Please note I did not include the quotes "" just the code.
This is what the file originally looked like:
#!/usr/bin/php
<?php
/**********************************************************************************
This is what I changed it to:
#!/usr/bin/php
<?php
chdir(dirname(__FILE__));
/**********************************************************************************
I also made sure that the file that I modified was set to have CHMOD settings of 755.
I did not come up with this code on my own. A guy that works for me told me what to try. As soon as I did it the piping started working.
I hope this helps someone else too.
Good Luck.
