       The SimplePie library included in WordPress RSS Feed Retriever is incompatible with PHP 8.0. Udating the SimplePie code to version 1.5.6 quickly corrects the problem.
   
       In case this plugin isn’t being maintained anymore, anyone encountering these issues can download the latest SimplePie source from https://github.com/simplepie/simplepie/releases/ and upload into the plugin’s lib/simplepie directory.
       ```
