“verifying that you are not a robot” when loading page

Hi,

Any idea on why sometimes when webpage is loading, there is a notice “verifying that you are not a robot” and it has only started to appear lately – we are using a CookieYes plugin, but this problem has never appeared before. We tried disabling it and the notice still shows. We are not using any other verifying plugins and have updated all the latest versions of all plugins. It does this on any browser and mobile devices. It takes up to a few seconds and then redirects to the webpage as normal. What could be causing this?

The page I need help with: [log in to see the link]
