We are in the process of setting up a new 2013 farm.
We have some PS scripts that will build it out similar in structure to our old 2007 build.
We are trying to build a template site for intitial roll out to pre-populate the sites with some Apps (i.e. calendar, etc.).
Started with the initial Site Collection and learned the hard way about the Publishing Infrastructure piece.
Created a new Site Collection based off of the Team Site. I am guessing Publishing is turned off by default in 2013. Verified Publishing was not on at the Site Collection or Site level. The page opened fine. I went into settings, Save Site as a template is available. Nothing has been added to site. However, I get the "Sorry, something went wrong." I tried to do it via "_layouts/15/savetempl.aspx", a suggestion from Google, and it did not work.
Tried the above only with a Community Site and it did not work either.
Checked the features turned on at the Web Application level and nothing screams turn me off.
Is there a nerd knob I missed? Most GoogleResearch focuses on the Publishing Aspect of it.
