GoDaddy Hosting Instructions:
(thanks to RonDawes)

Download the IonCube loader specific to your server. For convenience, we’ve created a package for GoDaddy users with only the loader files you will need, you can download it http://www.geodesicsolutions.com/downloads/ioncube_for_godaddy.zip .
Un-Zip the loader package you just downloaded, and upload the entire ioncube/ directory using BINARY MODE to your home directory using FTP.
If there is not one already, create a file named php5.ini in your home directory. This should be the top level directory you can access using FTP. (this is also where you should have uploaded the ioncube/ directory to in step 2) You should now see the file php5.ini and a directory ioncube/ when you FTP to the home directory on your server.
Edit the file you just created, and add this line:
zend_extension = /home/content/m/y/w/mywebsite/html/ioncube/ioncube_loader_lin_5.2.so
In the line you just added, you will need to change it to match your site. If your domain name is “www.example.com” then you would change it to be “/home/content/e/x/a/example/html/ioncube_loader_lin_5.2.so”. If you are having trouble, you can also find what the path is, by logging into our client area and looking at the license details. The license details will have the path that the Geo software is installed in, you will not use the whole path, but the first part will be the same (for instance, the Geo software may be installed in a sub-directory of your home directory).
Save the changes and upload the php5.ini file. Now access your site and see if it is working. If it is still not working, you may need to adjust the path as described in step 5, if you are having trouble with that contact GoDaddy support and they will be able to tell you what your home directory is. (Note that Geo support will not have access to that information, only your host will be able to tell you what your home directory path is)
