Strange withe space at top of some pagesI

HTML & CSS

In the website some pages have a strange white space line at top.I have done a html validation and w3c validator gives the following error:

Warning Byte-Order Mark found in UTF-8 File.

The Unicode Byte-Order Mark (BOM) in UTF-8 encoded files is known to cause problems for some text editors and older browsers. You may want to consider avoiding its use until it is better supported.

After some research i found that this might be related to my problem.

My question is: how to disable BOM?
I am using netbeans IDE for coding the website.

Hi,

Sorry I don’t know anything about netbeans but usually that will be an option in your editor when you save the file.
