The [[ https://www.mediawiki.org/wiki/Content_translation/Setup | set-up documentation ]] has some confusing aspects that makes it hard for people to get the system up and running:
[ ] It focuses on cxserver and does not describe how to configure ContentTranslation extension.
[ ] It does not include instructions to check that the cxserver is up and running (e.g., check you can access http://.../v1). Otherwise it is easy to access the root url and get a "Cannot GET /" message that makes you think that something is wrong.
[ ] It mentions //4. Configure cxclient's wgContentTranslationServerURL to 127.0.0.1:8000// but the "wgContentTranslationServerURL" variable seems to be deprecated.
