Hi there,
To get more information about the problem please try the following:
1. Check the browser console:
If your are using Chrome: Settings > Tools > JavaScript Console:
https://developers.google.com/web/tools/chrome-devtools/debug/console/console-ui
and check if there is an error there
2. Check the debug log:
It would be good if you can provide me the WordPress debug.log.[
To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:
define('WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true );
In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.
Also to narrow down the root of the problem you can do this test:
3. Minimal setup:
***Backup your site and DB before proceeding***
-Deactivate all the plugins but WPML and its addons
-Switch to a default WP theme (Twenty Sixteen for example)
-If the issue is gone, reactivate one at a time to see with which one is the conflict
Finally, make sure the memory of your site is enough:
4. Memory:
***Backup your site and DB before proceeding***
Add this code to your wp-config.php to increase WP memory:
/** Memory Limit */
define('WP_MEMORY_LIMIT', '256M');
Paste it just before:
/* That's all, stop editing! Happy blogging. */
These settings can be limited directly by your hosting provider, so I recommend you to contact and ask them to modify them directly. If you can get even higher values It would be great.
