Preview could not load due to the iframe response being incomplete; assign a menu

[shkake]

Hello,

So I get this error message when I click on “assign a menu” in cornerstone. I enabled the debug mode and this is what it says on my wordpress dashboard

but I don’t know what to do with that.

Thank your for your time,

Romain

Hello Romain,

Thanks for writing in! Based from the screenshot, you are seeing a PHP Warning. Usually these warning displays when a variable has been declared twice or display that it is null. You can get rid of these warning messages by disabling your debug mode. You can do this by opening wp-config.php and adding

define('WP_DEBUG', false);

/* That's all, stop editing! Happy blogging. */

When you revisit the page, you should no longer be seeing those messages. By the way, ​We recommend that you increase your memory allocated to PHP. To increase it, please edit your wp-config.php file and insert these lines:

define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

You can add it before the line
/*That's all, stop editing! Happy Blogging. */

If nothing is helping, provide us access to your site so that we can check your settings. Please create a secure note with the following info:
– Link to your site
– WordPress Admin username / password

define( ‘WP_MEMORY_LIMIT’, ‘256M’ ); define( ‘WP_MAX_MEMORY_LIMIT’, ‘512M’ );

I explained myself badly, what I wanted to say is that when I click on “assign a menu” in Cornerstone i get the following error message " The preview could not load due to the iframe response being incomplete. This is most often related to a pluging conflic, or customizations introducing a PHP error." So I enabled the debug mode. I think I did everything recommended for that kind of issue but it doesn’t seem to solve the problem. I’m going to add a Secure note, thank you.

Hello Romain,

Assigning a menu to the main menu area is not meant to be done in Cornerstone.

Please go to WP Admin > Appearance > Menus then create the menu there and set the menu as the Primary Menu.

Hope this helps.
