another new feature in version 15 is a problem checking page. This script basically checks many of your template settings and lets you know whenever there is a problem with any of your settings. To view this script, simply go to your Control Panel and you will find it at the bottom right – Check for problems.
It is a good idea to go to that page and check that every tick is “green”.
In the future I am likely to add more things and also offer direct solutions.
