I am trying to create a custom action to add a button to the ribbon that will send an email when clicked. The workflow is set for a manual start and associated with the list I want. I am only typing a name for the title, and “initiate workflow” and selecting my workflow for the type of action. However, when I click ok, I receive this message:

“Could not save the list changes to the server.”

I have full editing access to the SharePoint site. Does anyone have any solutions or ideas of what may be happening?

Thanks!
