Malfunction with "Articles Anywhere" from Regular Labs

I have installed the current version of the “Articles Anywhere” plugin and now I get the following error message when using it in the frontend editor

```
Warning
: Constant ASTROID_TEMPLATE_NAME already defined in
C:\xampp\htdocs\sgsn_site_new\libraries\astroid\framework\library\astroid\Template.php
on line 96

Undefined constant "Astroid\ASTROID_MEDIA_TEMPLATE_PATH"
```
