Hi there,
I just switched an in-progress site from single to multi-site. The subdomains all work as expected. The main site, however, no longer loads Pro content editor, header editor, options, etc. The loading animation appears, but nothing ultimately loads.
I noted that some people had a caching issue, but I’ve cleared all cache and still nothing.

Thanks for any help you can provide.
