Workaround


  • Make a full backup of your site.

  • Open your wpml-string-translation/inc/admin-texts/wpml-admin-texts.class.php file.

  • Look for the line 255

  • Replace: 
    	private function isAdminText( $key, $name ) {
		return null !== Wrapper::of( $this->getSubKey( $key, $name ) )
		                       ->map( [ self::class, 'getKeysParts' ] )
		                       ->map( invoke( 'reduce' )->with( flip( Obj::prop() ), $this->getOptionNames() ) )
		                       ->get();
	}


  • With: 
    	private function isAdminText($key, $name) {
		try {
			return null !== Wrapper::of($this->getSubKey($key, $name))
					->map([self::class, 'getKeysParts'])
					->map(invoke('reduce')->with(flip(Obj::prop()), $this->getOptionNames()))
					->get();
		} catch (Exception $ex) {
			error_log($ex->getMessage() . ' Option Key ' . $key);
		}
	}
