PHP Notice Error Messages

Hello,

I’ve noticed that after upgrading to the latest version of WP-Optimize, I am now seeing these errors in my nginx logs for admin-custom-login

PHP message: PHP Notice: Undefined index: login_custom_css in /var/www/kdb/wp-content/plugins/admin-custom-login/login-form-screen.php on line 106
PHP message: PHP Notice: Undefined index: login_form_position in /var/www/kdb/wp-content/plugins/admin-custom-login/login-form-screen.php on line 182
PHP message: PHP Notice: Undefined index: login_form_position in /var/www/kdb/wp-content/plugins/admin-custom-login/login-form-screen.php on line 195

I was also seeing them for social links and it was causing nginx to throw a 503 error and not allow login unless I removed the plugin manually. However I resolved that by reverting a VM snapshot and setting “Enable Social Icons” to “No Icon”. However I still get the above PHP errors

PHP message: PHP Notice: Undefined index: social_digg_link in /var/www/kdb/wp-content/plugins/admin-custom-login/css/socialcss.php on line 13
