All-in-One Event Calendar: CSS compilation failed because you don’t have enough free memory (a minimum of 24M is needed). Your calendar will not render or function properly without CSS. Please read this article to learn how to increase your PHP memory limit.

I'm migrating my website to a new server.  The site runs fine on the old server, but the new server is having issues with the calendar displaying.


I've tried all the solutions I've been able to find online.

Increased memory_limit to 256 MB


Added these three lines to my wp-config.php (above the settings include):

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


Deactivated all my plugins.


Changed calendar themes.


Reverted to older versions of this plugin.


Saved settings.


I'm having no luck.  Any additional ideas?
