 * I am facing also a problem with the plugin!
 * I get the following two messages in my woocommerce
 * _This site was reached as [http://www.apoteko.se](http://www.apoteko.se) ( according
   to PHP HTTP\_HOST ) and there are no settings present for this domain in the 
   WP-FFPC configuration yet. Please save the » WP-FFPC Settings for the domain 
   or fix the webserver configuration!_
 * _WARNING: you’ve entered username and/or password for memcached authentication(
   or your browser’s autocomplete did ) which will not work unless you enable memcached
   sasl in the PHP settings: add `memcached.use\_sasl=1` to php.ini _
 * What is that and how can I fix it!
 * Thank you

 * first: check if the webserver is forwardig the correct host to your site. If 
   the $_SERVER[‘HTTP_HOST’] variable is not apoteko.se, it will not be able to 
   save it correctly.
 * second: your browser autocompleted the username/password on the Backend Settings
   tab. Remove it.

 * Hi Peter!
 * For the 1st answer, I am not sure where can I check that. Do I find it inside
   the plugin in wordpress or in some forlder?
 * For the second, I have removed both uswername and password and save but when 
   I refresh it comes back. Althought the message stopped appearing now.
 * Many thanks

 * As the error log entry mentions, it’s your webserver configuration, not the plugin.
