Here's a response I got from matukio:
1st issue: Your template sets an hover color (don't ask me why) for admin forms, which affects also the form itself.
#adminForm .btn:hover, #adminForm .btn:focus, #adminForm .btn:active {
background: #fab325;
border-color: #fab325;
color: #ffffff;
}
Just remove line it from:

2nd issue: You don't have any events / dates published where I could check it. Normally that error only shows up if the address (google location) is not correct.
Can you create an event, which is accessible for me where it shows up?
Best,
Yves
