[Plugin: TDO Tag Fixes] Going to Page 2?

You can completely switch paging off following this idea.

If you don’t need to distinguish categories it is simply that (to be put into functions.php):

add_action( 'parse_request', 'show_all_entries_in_category' );

function show_all_entries_in_category( $args ) {
	if( isset( $args->query_vars['category_name'] )) {
		$args->set_query_var( 'nopaging', true );
        }
}

Thanks for your reply, but I need to idstinush between categories. Also I have alot of posts so need to have paging.
