 * Hi Mark,
 * I’m starting to plan for PHP 7 migration and ran the “PHP Compatibility” plugin
   on my site. It reported a few warnings and errors:
 *     ```

       ```
   
 * The errors show up also when scanning for PHP 5.5 and 5.6; the warning only shows
   up for PHP 7. Just wanted to make you aware. I’ll not migrate before March 2017
   so no hurry!

 * Hallo Anders,
    Wie geht’s dir? I am aware of the class constructor issue – the
   WordPress world has been warning us for some time. I am weeding them out, slowly.
 * I don’t quite understand the __DIR__ warning. This ‘magic constant’ was introduced
   in version 5.3. I’ve encountered issues with it in earlier versions of PHP, but
   it’s supported since 5.3. Maybe have a typo … __dir__ vs. __DIR__. I’ll take 
   a look.
 * Thank you.
    -Mark
