After changing the SharePoint site title, pages such as Manage App Deployments and Activate Site Collection hang indefinitely on "Working on it".
Indefinite loading on App Management pages. When an F12 trace is run on this loading page you will see the following console error:
"Uncaught error: Sys.ParameterCountException: Parameter count mismatch."
If you are experiencing this issue, contact a K2 Support engineer who will check your environment and verify if this is a known issue. From there, you will be provided a new K2 for SharePoint App from our Labs team that you can re-add to resolve this.
Please note that if you are experiencing a DNS error when attempting an App Deployment for this new app, this could be because you have updated your site URL without linking it to the correct server. Please make sure all updated site URLs are linked correctly.
