Above is a section of code that displays perfectly well in live view and in a browser when I use it on my own machine.

However, when I upload it to my website, it only displays the page down to where the smily is.

I assumed that the error is due to a small difference in the php variants, but it could also be something that is wrong with my code.

Can anyone help?

I am using Xamp 2.5 on my home machine. The web server is using php version 6 but version 5 is also enabled.

Its all written in html5 and php.
