Hi.
Surprisingly a page no longer displays - just all white screen.
When opening the corresponding page (a layout actually) in cornerstone I get the following error: The preview could not lad due to the iframe response being incomplete. This is most often related to a plugin conflict, or customisations introducing a PHP error.
I checked the common issues (https://theme.co/docs/common-issues#disabling-cache) so have tried hints like:
Updated everything.
Disabled all other plugins.
Removed single CSS on page and global CSS (no JS).
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.
No change, unfortunately.
Please advise. Login credentials in secure note.
