 * Hi there,
   Could you tell me the version of the plugin you’re using which give
   this warning?Can you also describe the scenario where you see the warning, some
   basic detail.Often a warning is just that and doesn’t affect functionality but
   it’s good to be sure.Once I have the context I’ll be better able to comment on
   any negative implication.Best regards,Nick

 * Hi Nick,
   Thank you for your time. The plugin version is **1.25.6**, PHP **7.4.
   x** and WordPress **6.8.1**.

 * Hi there,
   Thank you, I’m happy to help.I’m looking to understand when you see
   this message, what action causes this?Are you attempting to delete backups from
   your Existing backups for example?Sorry to have to ask, it’s just quite difficult
   not being able to see the scenario.I would mention you should upgrade PHP as 
   7.4 is no longer being supported.This could result in both security risks and
   potential compliance problems too.Best regards,Nick
