 * Hello all,
 * Our website appears to have crashed. Everything but the background image and 
   an error message (below) is gone:
 * Fatal error: Class ‘WP_Bootstrap_Navwalker’ not found in /home/jkakarat/public_html/
   wp-content/themes/jkabrisbane/header.php on line 5
 * There appears to be a php update that needs – would this have anything to do 
   with the error message?
 * I called our domain server holders (crazydomains) and they stated it was something
   to do with the theme that may have been updated. They mentioned that there is
   a way in wordpress to remove or revert recentally installed themes/updates, however
   I can’t see where this is and I am scared to go around making changes and possibly
   making it worse.
 * Would anyone be able to point me in the right direction? I am stumped on as to
   how to fix this or what this means.
 * Thank you in advance for any help.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-error-message-190%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
