 * [@darkidk](https://wordpress.org/support/users/darkidk/) thanks for reaching 
   out.
 * Can you try these steps to troubleshoot your problem?
 * 1. Disable all other plugins, then check for the fatal error. If it goes away,
   turn your plugins back on one-by-one until you start seeing the error again. 
   Then note the plugin that caused this error and get in touch with us.
 * 2. If the plugin step above doesn’t help, try activating Twenty Twenty temporarily
   as your theme. Then check again. If it starts working, likely something in your
   theme is broken or incompatible with recent versions of Jetpack and you should
   get in touch with your theme’s author.
 * Let us know what you find out!

 * Problem solved.
 * I deactivated jetpack, and activated it again.
 * Problem is solved, it seems to.
