Preview not the same as live website


I am having a few problems with my website and looking for help. In the preview mode it looks exactly like I want it to but on the live mode various pages have issues with formatting etc.

Is anyone able to help? Here is a link to the preview and live screenshots.

1. Home page the image and text is not centred in the live version
2. Our work page the logos end up in a bulleted list
3. About us photos end up underneath each other
4. News articles also appear in a list

The page I need help with: [log in to see the link]
