Apache "404 not found error"

Question

I previously posted a similar question because I used to get a 403 error message (Forbidden). So I decided to get a new micro SD card, and I installed a fresh Apache server then I re-followed this tutorial from scratch again

http://raspberrywebserver.com/cgiscripting/rpi-temperature-logger/

The python files work perfectly, no errors at all. However, I am not able to see the webpage, I get a "404 Not found" error.

I have to mention that the home page (my Raspberry Pi IP address) shows Apache's message "it works". I get the "Not Found" error when I try to access http://localhost/cgi-bin/webgui.py . This makes me think that the problem is related to webgui.py file that I have in the /usr/lib/cgi-bin directory. The owner of this file is www-data.

Below is the content of the error log file:

I just figured it out, what I did is I added this line

Require all granted

between the directory tages to the etc/apache2/conf-avilable/serve-cgi-bin.conf. Then I added the following line to the /etc/apache2/apache2.conf file:

ServerName localhost

Then

a2enmod cgi
service apache2 restart

Apache "404 not found error"
