Internal Server Error

The error message Internal Server Error sometimes is the result when a Php script is executed and the script, or the directory it is within, is set to a higher write permission value than the web server is configured to allow. This can affect the following LinkMachine scripts:

linkmachine.php
link_exchange.php
auto.php

Using an FTP program, set the write permission value of the affected script to 664. If that does not solve the problem, try 644. If that also does not solve it, try 444.

Also try changing the write permission value of the directory that the script file is located within. Try the values 775 or 755.
