Version - WordPress 4.7.12 running Twenty Seventeen theme with Plesk Onyx has Web Windows Hosting Application
Error When I login into Dashboard and select "Update" option for upgrading WordPress installation to 5.1, it loads for some time and then shows an error message:
The page cannot be displayed because an internal server error has occurred.
There's no other text except for this.
Wha I've tried so far
I attempted to enable logging by adding the following three attributes into the wp-config file, but no debug file gets generated into the wp-content folder. I checked IIS logs, but couldn't see logs file updating.
define('WP_DEBUG', true); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', true );
Deactivated all plugins - Problem persists
Please suggest options to fix this or get more details.
/var/logdirectory and do atail -fon your error_log which would be under a directory like apache2 or httpd, etc. Make sure you can run theindex.phpfile directly. Try aphpinfo.phpfile with a call tophpinfo();and see if that works. Generally this type of thing usually comes down to wordpress config like setting up your database properly.The error would be in your php error log. Try alsoerror_reporting(E_ALL);ini_set('display_errors', 1);
