WPML

Problem:
If you're using the WPML plugin with the Avada theme and WP Hide & Security Enhancer Pro, you might encounter an issue where you cannot save options for individual languages when the 'Create a new admin URL instead of the default /wp-admin and /login' option is activated in WP Hide & Security Enhancer Pro.
Solution:
We recommend you try the following workaround until the next WPML release addresses this issue:
1- Edit the

sitepress-multilingual-cms/classes/language/Detection/Ajax.php

file.
2- Replace the existing code:

private function is_admin_action_from_referer() {<br />    return (bool) Maybe::of( $_SERVER )<br />                       ->map( Obj::prop( 'HTTP_REFERER' ) )<br />                       ->map( Str::pos( '/wp-admin/' ) )<br />                       ->getOrElse( false );<br />}

with:

private function is_admin_action_from_referer() {<br />    $adminSlug = basename( trim( admin_url(), '/' ) );<br /><br />    return (bool) Maybe::of( $_SERVER )<br />                       ->map( Obj::prop( 'HTTP_REFERER' ) )<br />                       ->map( Str::pos( '/' . $adminSlug . '/' ) )<br />                       ->getOrElse( false );<br />}
