Hi There,
Thanks for writing in! Could you please try adding the following code into your wp-config.php file below the following line of code define( 'WP_DEBUG', true );.
define( 'WP_DEBUG', true );
if ( WP_DEBUG ) {
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
}
This will create a log file under your wp-content directory named as debug.log. Then you can activate cornerstone and perform some action on your site which will record any error messages in the error log file. Then check your log file and let us know what’s been recorded.
For further investigation, we also require your FTP credentials.
Let us know how it goes!
Thanks!
