 * After I installed Formidable Forms plugin, I’ve received ‘Fatal error: Call to
   a member function dispatch() on null in /home/saudecor/public_html/wp-includes/
   rest-api.php on line 278’ mensage.
 * I can not do anything on my website.
 * How can I solve this problem?

 * Hi there,
 * It sounds like you are running an old version of WordPress. Can you please update
   to the current version?

 * How can I update since all wordpress pages are not displayed? Is there any way?
   All pages show that error. I can not access neither modify configurations.

 * You’ll need to disable Formidable via FTP. Go to the wp-content/plugins page 
   via FTP, and change the name of the formidable folder to something else like 
   formidable2. Now you can access your site and update WordPress. Now change the
   folder name back to formidable and activate the plugin.

   it’s not working.
