Javascript/button error

Hi, I use RevCMS and my developer tools gives me these errors.

Further to this, buttons don't work, like the one in account settings to save changes.

Thanks

Has it just started doing this or has done it since you started using revCms?

It's hard to tell without having revcms myself, but i suggest on following the errors.

Well, if you can read you can find the error.
Just read the error that it's displaying, click it then it will open another window which will explain whats wrong.

'null' mean there's nothing in it. If you declare a variable and don't initialize it then there's null in it. If you want to do stuff with it then you'll get an error. Check why it's null.
