We cannot load the Banking tab. We can access Rules, Tags and Receipts but when we click on 'Banking' nothing happens.

We are accountants. This is not only affecting our bank account and we also cannot access our clients banking either. The staff who have their own logins are unaffected. I've tried multiple links to the bank feed (left hand navigation, clicking from the dashboard etc..) but get the same result of nothing happening when links are clicked. Please help!
