i had the same problem and fixed this by converting the file from utf-8 to utf-8 without BOM

If your files are encoding with UTF-8, better to encode them with UTF-8 without BOM. This can be easily done through notepad++. The steps are as follows,

1. Open your files in notepad++.
2. Go to Encoding option on the file menu.

This may resolve your problem.
