Hi I'm getting 3 or 4 error messages a month (as below) and I'm wondering if anyone can tell me whether this is due to an incorrect configuration of the PayPal plugin. They could be unauthorised attempts to access my installation, which aMember is preventing. However, I'd like to know for sure as I wouldn't like to be missing sales.
