I made following plugin and now the default welcome panel is skipped.

function hide_welcome_panel() {
	$user_id = get_current_user_id();

	if ( 1 == get_user_meta( $user_id, 'show_welcome_panel', true ) )
		update_user_meta( $user_id, 'show_welcome_panel', 0 );
}

add_action( 'load-index.php', 'hide_welcome_panel' );

However, the front page does not work properly yet:
– Jetpack statistics panel is empty
– Wp news panel contains just a text “Loading…”
– Not possible to make any kind of modification to front page, i.e. move panels, change screen settings, open help etc.

Any idea what could be the problem?

I read somewhere that changing PHP config could help in such cases (not done before). I wonder, if somebody could explain shortly why this could help?

As the actual blog/website works fine I hesitate to make any major changes without knowing why I’m doing those and what are the potential risks.
