 * Hi,
    I’m using Master Slider since year and never had a problem until now. Suddenly,
   my webpage found a problem with Master Slider. I deactivated it and when I try
   to activate it again, it says following, which is the same my webpage said when
   trying to load the plugin until I deactivated it:
 * Plugin could not be activated because of a fatal error.
    Fatal error: require_once():
   Failed opening required ‘/homepages/29/d390402709/htdocs/app390402726/wp-content/
   plugins/master-slider/includes/init/define.php’ (include_path=’.:/usr/lib/php5.6′)
   in /homepages/29/d390402709/htdocs/app390402726/wp-content/plugins/master-slider/
   master-slider.php on line 45
 *  My plugin should be updated (last update one month ago).
    I appreciate any help.
   Thanks a lot, Alberto

 * Hi Alberto,
 * Thank you for choosing Master Slider.
 * Please delete the plugin and install it again. Your sliders’ info will not be
   removed.
 * Let me know if the problem persists.
 * Best,
    Averta
