error message and staging version won’t show

Hi @ingridbsi

Try to disable WP_DEBUG Mode on the staging site by adding these lines in wp-config.php file of the staging site:

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

If that doesn’t work, then please share your website’s system information from (WP STAGING > System Info) via this form and we will help you further from there.

Thanks,
Alaa
