Yes, so did I until I looked into a little further! Somewhere in your Bluehost web folder, you should have a php.ini file. In there search for debug and you will find a debug display setting in there set to false - change that to true.
Now, bluehost allows you to select php version per website - you will find that in the control panel php settings. You might see what you have set there and make sure that you are using the 5.4 version for your websites.
