e) How do I get cleaner URLs?
Go to ACP > System [tab] > System Settings > System [tab] > Search Engine Optimization.
There, set both Redirect to new friendly URL format and Use .htaccess mod_rewrite to Yes, and save the settings.
Below Use .htaccess mod_rewrite, there should be a message to 'add a file called .htaccess with the following contents.' Copy the contents that it is referring to, into a text file.
Download /public_html/.htaccess and make a copy of it.
Open one copy of that file, and in it, paste the copied contents from step 3, to the top of the .htaccess file.
Then save the file, and upload it to replace the original at the location specified in step 4.
Go to ACP > Other Apps [tab] > Content > Settings > Advanced.
There, set Use .htaccess mod_rewrite to Yes, and save the settings.
You will need IP.Content for this.
