I'm having trouble making this solution work in localhost. I followed the steps precisely and I'm confident about it since I've made it work many times before while NOT in localhost. But when in localhost, I get this error:
Error loading data from server: apierror-visualeditor-docserver-http: HTTP 500.
I enabled all error reportings but I can't seem to get any more info than that. Anyone know what could be the cause, the solution, or a way to get more info?
