 * I made an SFTP connection to rename the jetpack folder to something else in order
   to disable the plugin. The critical error still happened. The debug details showed
   the issue was now happening in mu_plugins/endurance
    so I renamed the mu_plugins
   folder to something else.
 * This resolved the issue for me. I was able to login to the wordpress site. I 
   have renamed the jetpack back to what it was. I have not activated the jetpack
   plugin though.

 * Hello
    Thank you for your responses I went into ipage dashboard to get the ftp
   login info Then I used filezilla to make an ftp connection to my site I rename
   the jetpack plugin folder to disable jetpack. The debug info then showed the 
   issue in ‘endurance’ file located under folder mu_plugin So I renamed the mu_plugin
   folder
 * That fixed the problem for me.
    The wp-admin then opened correctly for me. Once
   logged into wp-admin, I deleted jetpack plugin I have also removed other plugins
   that I was not using
 * Thank you again for your help
