Error when enable k2 workflow rest service

Hi,

Do you receive similar error message when enabling SmartObject OData API?

Do you get any certficate warnings when browsing to this URL? 

http(s)://k2_site_url/api/odata/op/refresh

hi  @khanh ,

Thanks for your reply.

We didn't change anything then clicked the apply changes button, no error prompted so we think k2 maybe cache something.  But when we browse the "https://xxx/api/odata/v3/" and "https://xxx/api/odata/v3/" url, it prompted as below:

"Message": "The Workflow API in K2 has been disabled, please use K2 Management to enable it."

{"Message":"The OData Service for SmartObjects in K2 has been disabled, please use K2 Management to enable it."}

  We have enabled the service in management. Do you know how can we resolve this issue?

Thanks very much.
