Whatever you did, the manually configured URL works and error has been corrected. Thanks!
I wondered whether IPS had a login counter. Ok, I'll play around with configuring such a rule using the integer data field.
For the meantime I was playing around with a simple login redirect to the Calendar. With a rule that a Member is logged in, I created another rule (Boolean) of true with a 1 is less than 2. The threshold value is set to 1.
On a test account with more than 1 login sessions, when I set the rule to less than 1, I do not get redirected when I log in. However when I set the rule to greater than 1, I get redirected to Calendar when I log in. Both results were correct. If IPS does not have a login counter, or some method to know whether a member has logged in or not, the rules should not have worked, but they did. How is that possible?
