JSONP mode is on by default. It will fetch main wiki pages in the
browser, without the server needing to make any requests. To turn it
off, add [feature_json] enabled = false to config.ini.
Captcha is off by default. It is a custom solution and is still
experimental at this stage. If you turn it on, please monitor the logs
to see how it goes! config.ini options are as follows:
[captcha]
enabled = true|false
log = true|false
ip_header = <header name set by your reverse proxy, like x-forwarded-for>
