Hi I've used Squarespace for my business website for years without issue, but this week my site has stopped loading. Clients / customers cant find it. It just says "this site can't be reached error connection timed out" I can still access it through the Account Dashboard. The Site address is www.smartandco.co.uk My domain name is still active. I can't find a way of contacting Squarespace to "talk" to anyone. Any suggestions? Many thanks
