Can no longer add pages using Admin Panel after upgrade to 1.1

After upgrading to 1.1 I can no longer add pages through the admin panel. When I click Add Page then Continue nothing happens. How do I go about debugging this issue? All plugins are updated btw

This was fixed in Grav Admin 1.1.1

speedy fix tested and working thanks

I installed the Update, but now the admin panel has a server error. Please look:

How can I fix this?

This should of been fixed already in the latest update v1.1.2 -

You might need to do a:

$ bin/gpm update -f

To update the admin plugin.
