[Resolved] WPML cannot connect to your site.

Hello,

I would need to see the detail of the error. You can see how to enable debug logging here:
https://wpml.org/documentation/support/debugging-wpml/

Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:
define('WP_DEBUG', true);

Edit your wp-config.php file and add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . 'https://cdn.wpml.org/error_log.txt');

This will create an error_log.txt file in your site's root directory. Please send me its contents.

Thank you for sharing the debug info, below you can see the two issues related to the error you are receiving

For the other error go to your database and locate the wp_icl_translations database table, and share a screenshot of it's structure with me.

Did you recently migrate your site or make any changes to your database?

The database is missing the AUTO INCREMENT and also it's indexes.

Can you please also review other tables in case they are missing indexes and AUTO INCREMENT ?

Do you have any recent backups ?

These are all the WPML tables that should have AUTO Increment enabled

I recommend trying to re-migrate your database first or reviewing your previous installation's database tables to see if they are ok.

The database at the moment is corrupted, this is not caused by WPML but a migration gone wrong.
