Jetpack causing critical error

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.

Same issue here!! Please help!

Hey @anurags, can you let me know if you tried the solution suggested in this thread (thanks @ddumondgmailcom for linking it!) too?

What happened when you re-activated the Jetpack plugin – if you tried that at all already?

Happy to investigate further for you if you still have troubles!

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
