Can't login into my dashboard, weird error

Hi, one of my bosses is trying to login in our dashboard but he is not able to. How can we solve this errors?

Hello @julian1, could you attempt to clear all browser cache and login again?
And if that fails could you try and login through another browser and see if the problem persists?

We already tried those things!

@julian1 can yous end us over the account email and project link to so we can try and reproduce the error ourselves? Thank you!
