group title not editable in backend/ es stops when createing a group in frontend

by creating a new group i get a strange behavior of easysocial.
using backend:
o new group -> choosing category works
o entering title text field is not selectable so i can not enter a title

using frontend:
o new group ok
o select category gives me an Error as you see in the attachment. It's german and means
"Redirection Error.
The called website redirects the query, so that it can never end.
This problem can occur if cookies are deactivated or denied"
