We've been using WP Review Pro plugin for more than one year now and we have been facing this issue from the very start. At first we thought that maybe you or Avada theme will come up with a fix but nothing yet which is very disappointing for me. So the issue that we are facing is when WP Review Pro plugin is enabled we couldn't edit our pages because the Avada's Fusion Builder gets all messed up. So whenever we have to edit a page we have to disable the WP Review Pro plugin first then we have to make changes in the page and then we re-enable the plugin. I would be very glad if you can look into this issue.
