 * Hi,
 * I can’t enable WP_CACHE after I installed the latest WP-FFPC on WP v4.1
 * so i have checked some information about server as below.
 * – Apache 2.2.15
    – PHP v5.5.20 – MYSQL v5.5.41 – memcached v1.4.22 – php-pecl-
   memcache v3.0.8
 * 1) WP-FFPC was reinstalled,
    2) ‘define(‘WP_CACHE’, true);’ was added to end 
   line of “wp-config.php” 3) ‘memcached.use_sasl=1’ was added to end line of “php.
   ini” 4) WP-FFPC was activated 5) a ‘Save Changes’ button to WP-FFPC settings 
   was clicked.
 * However, I can see messages as below.
 * WP_CACHE is disabled, plugin will not work that way. Please add `define ( 'WP_CACHE',
   true );` to wp-config.php » WP-FFPC Settings
 * 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
 * Thanks

 * Please try adding the `define ( 'WP_CACHE', true );` line to the beginning of
   the wp-config file instead.

 * Hi petermolnar
 * Thank you for your message.
 * now is normal after wp-config was applied the config.
 * but, I can see another error message as below.
 * 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
 * can you give me an advice ?

 * That was probably because some auto-fill forms functionality ( the error message
   do mention this scenario by the way ), I had it once as well.
 * WP-FFPC Settings -> Backend settings tab -> remove data from `Authentication:
   username` and `Authentication: password` fields and save it.
