hello,
we was change this line to keep the plugin secure,

the original line was:

$nonce = isset($_REQUEST[‘_wpnonce’]) ? $_REQUEST[‘_wpnonce’] : ”;

and the new line is:

$nonce = isset($_REQUEST[‘_wpnonce’]) ? sanitize_text_field($_REQUEST[‘_wpnonce’]) : ”;

so please make sure that the 2nd line is exists in the options_page.php (line 10)

thank you
