 * Plugin seemes not to be compatible with newer versions of WP (compatible up to
   3.8.10). Last update more than 18 months ago. Author doesn’t react here in this
   forum anymore.
    Plugin produces server error, nothing is displayed anymore. No
   further search for reasons due to lack of time. Alternative plugin installed.
   Bye.

 * I know I had a 404 permission denied error due to the settings in iThemes Security.
   If you’re running that, you need to uncheck several items in the System Tweaks
   section – Disable Directory Browsing, Filter Suspicious Query Strings in the 
   URL and Filter Long URL Strings

 * [@gjefle](https://wordpress.org/support/users/gjefle/): THX for your hint, iThemes
   Security is a possible cause, but disabling the extension or cripplung the settings
   is no real alternative. Meanwhile our customer changed to another plugin.

 * Plugin is now compatible with latest WP version.
 * I can’t support what other plugins may do to cripple this plugin, sorry.
