weeix on "[Plugin: Clicface Organi] Call to undefined function register_setting()"

Hi,

Thanks for creating this plugin.

My client said one of his sub-sites (in a multisite environment) is dead with error 500 both from frontend and backend.

So I disabled every plugins for that sub-site and tried enabling them one-by-one. By solely enabling Clicface Organi, I can replicate error 500 again. Here is the log from error.log when error 500 appears:

[Sat Aug 20 15:02:53.028211 2016] [:error] [pid XXXX] [client XXX.XXX.XXX.XXX:32461] PHP Fatal error: Call to undefined function register_setting() in /var/www/html/wp-content/plugins/clicface-organi/clicface-organi.php on line 31, referer: https://mysite.com/subsite/wp-admin/plugins.php
