gravity.cool "Invalid number of arguments to Solidity function"

[fafrd]

Hey, I'm trying to use https://gravity.cool/#create, but the Metamask connection doesn't seem to work.

In my console, I see the following-

Uncaught Error: Invalid number of arguments to Solidity function
    at Object.InvalidNumberOfSolidityArgs (inpage.js:17)
    at u.validateArgs (inpage.js:17)
