I am seeing this error on a List using Sharepoint 2013 (create new list, add item). Screen Response Text
is "Can not save item at this time", Fiddler shows a 401 on GET /_vti_bin/client.svc/ProcessQuery
then a couple of 302's and finally:
401 on GET /_windows/default.aspx?ReturnUrl=%2f_vti_bin%2fclient.svc%2fProcessQuery
If I try to RENAME a field I fall into this loop:
GET /_vti_bin/client.svc/ProcessQuery 302 redirect to:
/_login/default.aspx?returnUrl=%2f_vti_bin%2fclient.svc%2fProcessQuery
This redirect gives back a 302 redirect to:
/_windows/default.aspx?ReturnUrl=%2f_vti_bin%2fclient.svc%2fProcessQuery
This redirects back to:
/_vti_bin/client.svc/ProcessQuery
And this looping continues until I see the on screen message
Unexpected response from server. The status code of response is '0'. The status text of response is ''
YOUR MOVE. Thanks.
PS in the SP logs we also see:
