Hi,
I got the same issue. Empty the cache is just a temporary solution.
Failed to load https://api.beeketing.com/rest-api/v1/customers/ref_id/3?shop_id=9968383&_=1533537892593: The ‘Access-Control-Allow-Origin’ header contains multiple values ‘website link, *’, but only one is allowed. Origin ‘website link’ is therefore not allowed access.
