Strange characters appear in admin category and header cart.

Question

I am facing a very strange problem:

Whenever I go to catalog/category in admin area:

"c" letter is appear at the first, I know it cause this problem but I don't know how it was appeared.

Otherwise, "c" letter also appear on frontend:

When I was trying to delete an item in minicart, the response html also have c letter.

Please any can help me ?. My site: http://sites.magebuzz.com/wholesalersdirect. Enter the postcode as 2500 to redirect to product page.

Thanks you very much.

Check your index.php. Make sure you don't have a stray "c" at the top before the <?php.

If it's not there then try disabling CommerceBug. You may have a stray "c" in that extension somewhere.
