I have a page in which I display more than one grid.
If after the first grid I load the other in an iframe each, then it works fine.
If I try to load them without iframes, then I get this error:

Fatal error: Cannot redeclare class jqGridDB in path/php/PHPSuito/DBdrivers/jqGridPdo.php on line 4

Is there a way to avoid using an iframe? (if I do, I cannot use a dynamic grid height, because I get scroll bars for that iframe, and don’t know how to make the iframe stretch to take the whole grid without vertical scrolling)
