I get 'unexpected T_STRING' error

You may get this error because all .html files are parsed as PHP here. So, if your .html file contains "<?" or "?>" tags/text (which shows for file parser that PHP code started), you get this error. This can happen with XML files if they are not using correct content type. If order to fix this error you need to remove "<?" and "?>" symbols or entire lines with these symbols from your HTML page source.
