I am totally confused!
Here's what I do:
1. create new workflow
2. add 'request review' action to it
3. add myself as the reviewer and task description 'test'
Now I publish it and open the task and I get the error : This form cannot be opened in a Web browser. To open this form, use Microsoft InfoPath.
I am not even using InfoPath?!
I use Nintex 2013. Can anyone help me??
