[Closed] critical error

Hi Daniel,
Thanks for contacting WPML support.

1. To ensure the quickest and most accurate support, please provide your debug information so that I can get a look at some of your configurations. You can find it in WPML > Support > click on “Debug information” link. Please check this link for more info: http://wpml.org/faq/provide-debug-information-faster-support/

2. Please provide us with the WordPress debug.log, this will allow us to see if any PHP errors are being produced. More Info: https://wordpress.org/support/article/debugging-in-wordpress/

To enable it, open your wp-config.php file and look for:

define('WP_DEBUG', false);

And change it to:

define('WP_DEBUG', true);
// Enable Debug logging to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
// Disable display of errors and warnings which is recommended on a live site.
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors',0);

Then try to reproduce the issue by clicking the + sign again and check if any errors were saved to the debug.log log file inside the /wp-content/ directory.

If you can paste your debug.log to https://pastebin.com/ and provide me that link, it would be great!

Kind regards,
Mohamed
