Hi, I get this when trying to enter conerstone to edit language page after installed Polylang.
The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.
Origin URL: https://nordicadditives.com
Preview URL: https://nordicadditives.com/home/
I have tried all hints from the support like:
https and also installed one click ssl.
I have renamed .htaccess to -bak and updated the permalink.
I have added following to the wp-config:
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
define( ‘WP_MAX_MEMORY_LIMIT’, ‘512M’ );
I have cleared cache in windows.
Nothing works…
Help!
