Php upgrade error messages

Hi

I’m currently using PHP 7.4 version on my site. Upon compatibility scan with PHP 8.0 I found 30+ errors in multiple files of pixelyoursite plugin. I’m using latest versions of plugins. Error message is:

‘object’ is a soft reserved keyword as of PHP version 7.0 and a reserved keyword as of PHP version 7.2 and should not be used to name a class, interface or trait or as part of a namespace (T_NAMESPACE)

Please let me know what I should do

Regards.
