Not tested with wp 5.9.1

The plugin destroyed my entire site, once I installed the plugin not one website on my domain did it anymore. However, this was not due to the plugin but to my hosting provider. This has changed the settings and the plugin works properly again. Just a pity that the plugin has not yet been tested on the latest word-press version, but the plugin still works well on wp 5.9.1. I posted a dead link on purpose and within 3 days I got an email that a dead link was found. For a free application this is fine.
