Hey Kathy,
Thank you for reaching out to us!
We usually recommend our customers to keep their plugins up to date to avoid conflicts and have our latest features and fixes installed. We work hard to make our plugins broadly compatible. However, like all WordPress developers we cannot test with every plugin, theme, and server environment out there, and sometimes “conflicts” can occur.
I would suggest you to backup your site using a plugin like BackWPup or Duplicator and update your plugins after that. If for some reason you experience any issue after the plugin update, please reply to this thread and I’ll be happy to assist!
Regards,
Patricia
