When I try to include something that is in the main folder to some file that is in the subfolder, I get this:

Warning: main(): stream does not support seeking in /home/phrona/public_html/galleries/01/index.php on line 1

It works fine, but this warning appears at the top of the page. so I need:

a) How to do it without getting warnings

OR

b) command that hides warnings

Thanks
