 ===== Trouble Shooting =====
-If any of the demos fails, the most likely reason will be file permissions. Check that the resource ''$SERVER_ROOT/cgi-bin/echo_params.cgi'' is executable by the web server and also that the "hash-bang" line is correctly set to the full path of your installed Perl interpreter. The example PHP scripts with ''beer.php'' and ''echo_params.php'' need only to be readable by the web server.

-If these tips don't help, it would be worth noting the error message returned by the web server and looking into the server error log ''$SERVER_ROOT/apache/logs/error_log'' for a hint about what might be wrong.
+Another possible problem, especially on Unix-based operating systems (Linux/Mac) may be due to line endings. Ubuntu provides a package that provides tools to correct this:
+<cli>
+$ sudo apt-get install tofrodos
+$ cd /usr/bin
+$ sudo ln -s fromdos dos2unix
+$ sudo ln -s todos unix2dos
+</cli>
+Then change the line endings of the cgi-script:
+<cli>
+$ cd $CGI_BIN/cgi-bin
+$ sudo dos2unix echo_params.cgi
+</cli>
+If these tips don't help, it would be worth noting the error message returned by the web server and looking into the server error log ''sudo tail /var/log/apache2/error.log'' for a hint about what might be wrong.
