 * Hi,
 * I installed the core LearnPress plugin and upon Activation, it caused a Fatal
   error and I can no longer access wp-admin.
 * I have a backup so can revert to a saved version but would like to continue with
   LearnPress if possible.
 * Fatal error: Uncaught Error: Call to undefined function wp_get_current_user()
   in /home/zonev926/public_html/abundant-living-oils.com/wp-includes/capabilities.
   php:640 Stack trace: #0 /home/zonev926/public_html/abundant-living-oils.com/wp-
