Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

WordPress wykrył błąd w używanej wtyczce: WPML Multilingual CMS.

First, visit your website (hidden link) and check for any visible issues. Next, visit the page where the error was caught (hidden link) and check for any visible issues.

Hello,
Thank you for contacting WPML support.

1.- I would like to ask you to visit this link and follow the steps described: https://wpml.org/faq/prevent-performance-issues-with-wpml/

2.- Please increase the PHP Memory Limit. Minimum requirements are 128Mb: https://wpml.org/home/minimum-requirements/
You can add this to wp-config.php to increase WP memory:

/** Memory Limit */
define('WP_MEMORY_LIMIT', '128M');
define( 'WP_MAX_MEMORY_LIMIT', '128M' );

- Add it above the line /* That's all, stop editing! Happy blogging. */

Kind regards,
Carlos
