Adding a Website in Avast Exceptions still does not allow me to go to website

I have several websites that are in my favorites, that I received emails from every week and every time I try to access the website I am blocked. These websites are retail sites for meds, clothing, major stores etc. I have added the exceptions numerous times! What to do? Greta

Where exactly did you add exceptions?
Do you use the Avast browser or Chrome/Firefox/etc.
