WPML is missing some records in the languages tables and it cannot fully work until this issue is fixed.
Please go to the Troubleshooting page and click on "Clear language information and repopulate languages" to fix this problem.
This warning will disappear once this issue is fixed.
========================================
this error message keep appear, I've follow the step it mentioned, but not fixed, after that the "Clear language information and repopulate languages" even can't click again.
To enable the WordPress Debug log, open your wp-config.php file of site root and look for define('WP_DEBUG', false);. Change it to:
// Enable WP_DEBUG mode
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
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
In this case, the errors will be saved to a debug.log log file inside the */wp-content/* directory. Please visit the site backend pages like All Plugins and check if you are getting any errors or warnings related to WPML in the log file.
If you can paste your debug.log to http://pastebin.com/index.php and provide me that link it would be great! (This is the cleanest way because sometimes the logs are long and create a complete mess of discussion).
i can't reproduce this error, because it appeared immediately after installed WPML (a few days ago), now even can't click on "Clear language information and repopulate languages" any more. Therefore I can't do anything to make it happen again, because it has never disappeared. thx
Thank you for the updates. Please try the workaround suggested in the following ticket after a full site backup{mandatory} and make sure the issue is existing or not.
Thank you for the updates. The Debug log is not showing any warning or error from WPML on today's date.
So please try the following steps to remove the wpml_notices key from the options table and check whether the notice is still showing or not.
1) Be sure of having a full backup of your site before proceeding
2) Access to your database
3) Open the wp_options table
4) Look for the wpml_notices key
5) Remove it
