All-in-One Event Calendar: CSS compilation failed. Not enough Memory.

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 Timely All-In-One 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:

define(‘WP_MAX_MEMORY_LIMIT’, ‘256M’);
define(‘WP_MEMORY_LIMIT’, ‘256M’);
ini_set(‘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?
