 * I’ve just download a Facebook plugin for Facebook Pixel from this link:
    [https://www.facebook.com/events_manager/pixel/?act=10154234114374506&pixel_id=1011144225657942&selected_data_sources=PIXEL&pixel_dialog=woocommerce](https://www.facebook.com/events_manager/pixel/?act=10154234114374506&pixel_id=1011144225657942&selected_data_sources=PIXEL&pixel_dialog=woocommerce)
 * But when I clicked the ACTIVATE button, suddenly I got this message below on 
   my website. Now I have NO ACCESS to my website to deactivate or do anything. 
   HELP!
 * Fatal error: Class ‘WP_REST_Controller’ not found in /home/soluti15/public_html/
   paperprovision.com/wp-content/plugins/facebook-for-woocommerce/includes/fbcustomapi.
   php on line 15

 * Using either FTP or your website hosting login file manager, navigate to your
   website’s “wp-content/plugins” directory and rename or delete the directory name“
   facebook-for-woocommerce”
    This will disable the plugin. Fixing the problem may
   not be so easy. Ask for support on that FaceBook page, see what everyone else
   is doing, etc. For myself I am not sure that I would take a plugin from a facebook
   page and install it, potentially very risky. Do you know the authors ? What is
   their reputation ?
