403 Forbidden error

Hi,
I am unable to publish or generate template layouts. Saving layouts continues to return a 403 forbidden error. At first, I thought I thought this was something to do do with with my hosting service, but I have now had the same response across several different hosting accounts and each support service saying that it is an issue with the extension. Just wondering if anyone else has had the same experience and/or resolved the issue?

Hi
