wordress visual editor missing

I am running a wp multi-site, I am unable to edit pages or posts on sites other than the main site, the visual editor seems to be missing as does the text, however, if I highlight the text it is there in html. I am not sure why this is working on my primary domain, http://www.ilghub.org, but not the other sites i.e. http://www.midlands.ilghub.org.

I uninstalled all plugins, reverted to twenty-sixteen, reinstalled wp version 4.2 manually with no luck.
