I installed a content management system called Opencart, however when I click the continue button on the checkout page it doesn't work. I installed Firebug, but I am not even sure what I am looking for. I am a total novice in these matters, any assistance would be greatly appreciated. I have seen where other people have had the same errors, but there are no solutions to my issue online. Please let me know what additional information to add here. As I told you I am a beginner. I can read as many books as I want, but its all gibberish until I can make the connections.
