Avast stopped me using a popular website

Hello. I upgraded my out of date free Avast programme today, paying for 2 years subscription and 1 year of clean up. Instantly I can no longer access Ninjakiwi.com. i have been using this site happily for years. The only thing that changed was upgrading Avast.
I have tried adding this url to the exceptions and restarted my computer. I have tried the url on 3 different browsers. The site can not be reached.
Is there an easy fix for this?

If it was an Avast issue you would receive a blocked notification, the site is unreachable even without Avast so it’s a problem on the website’s end.

Hi velkanzi,
issue will be fixed in next vps update - FP.
Thank you for report !
