Could you please increase the WordPress memory limit (WP Memory Limit) to at least 256 MB? WPML requires at least 128 MB.
Your current values are:
PHP Memory Limit 1 G
WP Memory Limit 40 MB
To do this, you need to connect to your website's server and open the wp-config.php file in a text editor. The file is located in the WordPress root directory.
Add this code to the wp-config.php file to increase WordPress's memory:
define ('WP_MEMORY_LIMIT', '256M');
Add this just before this comment:
// That's all, stop editing! Happy blogging.
The current values can be viewed under WPML > Support > WordPress.
These settings can be restricted directly by your hosting provider. Therefore, I recommend contacting them and asking them to change them directly if the changes are not applied immediately.
If adjusting the limit will not solve the issue, please let us know.
