 * Hi there,
 * I have an issue that some of my pages, as well as my plugins list keeps coming
   up with a “Critical Error” message.
 * I have tried to deactivate my hummingbird plugin, as I know this plugin somewhat
   rearranges the database which I what I can assume the issue is somehow – I am
   not a programmer and this plugin was working fine but has completely broken some
   pages on my website. I try to disable but I get the error, it is up to date as
   far as I am aware.
 * Please help as I may lose business because of this critical error!
    I do not 
   use wordpress directly on .org, but instead have it installed on a hosting website.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fhummingbird-causing-critical-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Update:
 * I followed a step in this ticket
    [https://wordpress.org/support/topic/fatal-error-causing-wordpress-wp-admin-login-crashed/](https://wordpress.org/support/topic/fatal-error-causing-wordpress-wp-admin-login-crashed/)
   although my folder was named “Hummingbird Performance” instead.
 * and have managed to deactivate the plugin, but am very weary about re-installing
   it! What if this happens again, it seems to be a common issue which is upsetting
   as I was really enjoying the plugin.

 * Hi [@nhdesign](https://wordpress.org/support/users/nhdesign/)
 * Sorry to hear you had this issue.
 * The fatal error will return a line in the debug.log file, the best approach is
   reinstalling the plugin using a fresh copy and if the issue persists enable the
   debug mode following this guide [https://wpmudev.com/blog/debugging-wordpress-how-to-use-wp_debug/](https://wpmudev.com/blog/debugging-wordpress-how-to-use-wp_debug/)
 * This will generate a log file in wp-content folder which gives more information
   why the critical error is happening.
 * Best Regards
    Patrick Freitas

 * I will try re-installing and see if the issue is resolved.
 * Kind Regards
