Hello There,
Thanks for writing in!
Please make sure that you have inserted a valid and correct html. If ever there is a broken html, it will break Cornerstone and will switch to Skeleton mode. And perhaps you might also experiencing PHP memory limit exhaustion. 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.
