An unusual one for me, I am using Pro to redevelop an existing site (on a dev copy). it is on a VPS that I do not control or set up.
The problem is that the header builder will not allow me to create a new header to edit and gives me the error message
"Hey! unable to create new header."
I'll give login details & url in a private message below
Any help gratefully received
PS the client's set up is in Dutch so auto translates to English for me. not sure if that is relevant
