 * Hi, today we updated to wordpress last version and got this error (we use PHP
   7.3):
 * WP RSS Aggregator has encountered a critical error. The safest course of action
   is to deactivate the plugin and any of its add-ons on this site using the button
   below. Once you’ve done that, you may reactivate them and start using the plugins
   again. If the problem persists, please copy the below error and send it to our
   support team with an explanation of when and how it happened.
 *     ```
       Error Message:

 * Could you help us please?

 * I think the problem comes with the PHP version 7.3, that your plugin could not
   be compatible, is it? We changed our php version to 7.2 and error dissapeared,
   so seems to be the problem. Could you please update us on this?
