 * Hi, I’ve got an unusual error when trying to migrating my WordPress site from
   Bluehost to DigitalOcean. I’ve extracted the root WordPress folder to `var/www/
   html/mydomain`, set the Apache virtual host, imported database and adjusted the
   value in `wp-config.php`. I haven’t change anything except changing the domain
   value in `wp_options` from https:// to http:// (because I plan to disable http
   temporarily and create a new certificate after migration success)
 * When trying to access any page, including wp-admin dashboard, I got the following
   error which returns 500 response code.
 * `[php7:error] [pid 8715] [client 52.77.206.243:60722] PHP Fatal error: Uncaught
   Error: Cannot unset string offsets in /var/www/html/mydomain/wp-includes/widgets.
   php:1142\nStack trace:\n#0 /var/www/html/mydomain/wp-includes/widgets.php(1115):

 * The PHP version is PHP 7.2.10-0ubuntu0.18.04.1. WordPress version is 4.9.9
    What
   should I do to fix it?

 * Were you using different PHP version when your web was in BlueHost?

 * [@pramadiputra](https://wordpress.org/support/users/pramadiputra/) The PHP version
   in Bluehost was 5.6. I’ve tried to switch to 5.6 too in the new server but still
   got the same error
