Unable to update mashup
As a possible solution, I have also tried to duplicate it in order to use the new one. After clicking in duplicate, a new window has appeared with this message: "Could not load "New Mashup - 1". Reason: 404 - Entity Not Found : [New Mashup - 1]"
Then the new duplicate mashup has been created but the behavior is exactly the same that with the original one: "Unable to update mashup"
It only happens with this specific mashup, I have achieved to generate changes in other entities of the same project as other mashups, styles or media.
Any idea what could have happened? Any possible solution?
