Hi, I'm tring to develope an app in javascript for sharepoint.
It's a simple app which modifies the style of a tasks lists. The weird thing is that it's been working well but now when I try to run it again (without changing nothing in the code) this error is shown:
Only Content controls are allowed directly in a content page that contains Content controls
As I said it worked five minutes ago an I didn't change anything.
Any suggestions??
