Cornerstone plugin giving 503 error

[colonelmarketing]

I am trying to edit a page with Cornerstone but every time I try to save after an edit, the website freezes and the whole goes offline giving the 503 Service Unavailable error. It resolves itself after a few minutes but I am not able to save any page edits.

I disabled all plugins except the Cornerstone and the issue was still there so not a plugin conflict. I am using Integrity stack of X theme.

Hello Danish,

Thanks for writing in! There could be a fatal error in your site. ​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. */

We would loved to know if this has work for you. Thank you.
