Good afternoon! I work in a company that manages several sites (joomla - on different servers). All with the same header and footer.
From time to time, we need to change all the headers and footers of all sites.
This process, until then, is done manually. Thinking about the agility of this change process, I wondered if it would not be possible to create a server with this material and use some kind of include, so I do not have to change it one by one whenever it's needed.
I have researched here, but I have not found anything very conclusive. Can someone give me a light?
