Sourcerer returns "3 arguments are required, 2...

Dear developers,

I just installed Sourcerer on a website and whenever I click on the "Code" button when creating/editing a new Joomla content item, I get the popup but with a message saying "3 arguments are required, 2 given". Reinstalling the plugin didn't solve the issue.



Thanks kindly!
Best regards,
Dan

Yes, that was the deal - wouldn't have thought of this at all. Thank you!
