Undefined variable: temp

It looks like you need line

$temp = strlen( $_SERVER['REQUEST_URI'] ) - 10;

in front of line 227 of /wp-content/plugins/wp-slimstat/admin/wp-slimstat-admin.php:

if( strpos( $_SERVER['REQUEST_URI'], 'edit.php' ) !== false || ( $temp >= 0 && strpos($_SERVER['REQUEST_URI'], '/wp-admin/', $temp) !== false ) ) {

otherwise the following error message is generated when WP_DEBUG is on:

Notice: Undefined variable: temp in /wp-content/plugins/wp-slimstat/admin/wp-slimstat-admin.php on line 114
