I am trying to: paste a key

Link to a page where the issue can be seen:hidden link

I expected to see: registration should work fine

Instead, I got: Invalid site key for the current site.

Thank you for contacting WPML Support.

Please follow the steps.

1) Go to
2) Delete already registered keys from the list.
3) Click on "Add New site" button
4) Copy paste the entire URL of your site.
5) Try the new key.

Make sure https and www version of your site are handled properly.

Please let me know if that helps.

Also, I request you to update the WP Memory Limit to at least 128MB which is the minimum requirement for WPML:
Add this code to your wp-config.php to increase WP memory:

/** Memory Limit */
define('WP_MEMORY_LIMIT', '256M');
define( 'WP_MAX_MEMORY_LIMIT', '256M' );

Paste it just before:

/* That's all, stop editing! Happy publishing. */

Could you please add this code to your wp-config.php so we will get more information about the issue:

define( 'WPML_DEBUG_INSTALLER' , true );

before the line

/ That's all, stop editing! Happy blogging. /

After you enter this code, when you try to register, you will get message looking like this
hidden link

Also, can you please contact your hosting company and ask if their firewall is blocking access to API ( ) and our JSON : hidden link
