WPML Language Switcher Bug Workaround

sitepress.class.php-bug-amelioration.php

//
// referencing v3.1.5 of WPML sitepress plugin
// in file: sitepress-multilingual-cms/sitepress.class.php
// at or near line: 5898 (inside method `convert_url`)
//

Add these three lines of code after the first larger if/block.

if ( is_null( $code ) ) {
	$code = $default_language;
}

so.... the function should begin this way:


	function convert_url( $url, $code = null ) {
		if(!$url) return false;

		$default_language          = $this->get_default_language();
		$language_negotiation_type = $this->settings[ 'language_negotiation_type' ];

		if ( is_null( $code ) && $language_negotiation_type == '2' && isset( $this->settings[ 'language_domains' ] ) ) {
			foreach ( $this->settings[ 'language_domains' ] as $lang => $domain ) {
				$domain = preg_replace( '/^https?\:\/\//', '', $domain );
				$domain_data = explode('/', $domain);
				$domain = $domain_data[0];
				if ( $domain == $this->get_server_host_name() ) {
					$code = $lang;
				}
			}
			if ( is_null( $code ) ) {
				$code = $default_language;
			}
		}
		// -- BEGIN HACK --
		if ( is_null( $code ) ) {
			$code = $default_language;
		}
    		// -- END HACK --
    
		if ( is_null( $code ) ) {
			$code = $this->this_lang;
		}
