I was checking out a ftp program that is made with PHP below it worked good for couple times then I get the "HTTP 500 Internal Server Error" and I checked my server logs and found in the cgi.log this error
"CGI: ["C:\Program Files\PHP5\php-cgi.exe" ftp.php ] URI: /ftp.php Broken pipe"
I tried to email the author of the program but got no reply and the strange thing is my forum and every other php type page on my site works fine just this program stopped my powered by Abyss is here the idea for this program was to let people upload pictures the thing they were going to sell and like I said it worked really good afew time then it crapped out. Can anyone see what happened with this code below? I tried looking it over but I'm very new when it comes to figuring out php
Thanks for any help
Tom
