Error ini terjadi pada instalasi wordpress menggunakan autoinstaller milik masterweb dalam paket spanel. Paket wordpress yang diinstall masih versi 3.8, dan ketika diupgrade ke versi terkini so far so good. Tapi muncul pesan error pada bagian footer yang cukup mengganggu, karena pada pesan itu ada username akun hostingnya. Pada bagian /home/sloki/user/XXXXXXX/, huruf x itulah username hostingnya.

Warning: An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums. (WordPress could not establish a secure connection to WordPress.org. Please contact your server administrator.) in /home/sloki/user/XXXXXXX/sites/bakesbangpolkabgarut.com/www/wp-includes/update.php on line 295

maka, downloadlah wo-config.php pada root wp.

setelag FTP_PASS tambahkan baris ini

define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
