Problem:
When adding a language switcher to the top menu there is a warning in the header of the site even with the debug mode set to false in the wp-config.php.

Solution:
This is not an error but a warning from the debug mode.

To prevent it showing online changed the lineof your wp-config.php file to hide the errors from the visible areas of the page but still be able to check the debug error information.

Replace this:

define('WP_DEBUG', false);

With this:

define('WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY',false);

The first line enables de debug mode, so PHP errors for WordPress can be tracked. If you don't want to activate the debug log, set this instead:

The second enables to create a text file called debug.log in the directory wp-content, where you can see the errors of the site.

The third line hides the errors from the page so you don't get disturbing errors in the frontpage.

That does not mean that this warning is gone, it just is not visible any more and you are still able to check any errors in the future..

Problem:Language switcher shows current language.

Solution:We have this option but it's available for the language switcher that is the list of the languages. A dropdown language switcher will always have the currently active language unless you create a custom language switcher.

If you have the list of languages as your language switcher, go to WPML->Languages and edit your language switcher. To remove the currently active language you need to disable the "Current language" option in the "What to include in the language switcher" section.
