I am getting the above message when I am trying to amend my template and display the amendments.
I saw Ticket #29092
Which is very similar to my problem. I don't get blocked but I can't update my template.
The customer finds a solution which he says " After I "Allow Site Templates" (since I use more than one template) it is working fine again"
But I can't find that option.
One other note I have is that I use Mobile Broadband and my IP address can change each time I logon , is that linked to the problem?
I have attached the messages I get
