Hello, there.
It sounds like something was conflicting with your Jetpack plugin installations.
Would you be able to delete the /Jetpack/ folder from inside your /wp-content/plugins/ directory? You can do so by accessing your server through FTP access. Bluehost can assist you again if you need additional help.
Afterwards, it would be a good idea to make sure that all of your plugins, theme, PHP version, and core of WordPress are all updated before trying to install and activate Jetpack again (Blue can also help with all of that). It should not give you this same error, but if it does, try removing Jetpack once more and deactivating all of your other plugins before installing and activating Jetpack again, but by itself this time before turning your other plugins back on.
Please let us know the results of this troubleshooting and we can go from there. Thanks!
Hi @madhattersez , I’m having the same issue and GoDaddy have said as they can see all my plugins, themes, PHP version and core of wordpress files are up to date. They suggested I updated my core plugin files (have no idea what this means), are you able to help. This is the message I’m getting

Thanks!
Hello!
I did as you asked and the same error comes through. Everything is up to date and updated – and when I install Jetpack first the error returns. If I slowly install all the plugins first and then Jetpack last, the error appears only when I activate Jetpack again. As 4mish4 said, Bluehost told me that the error I get is exactly the same one, starting with:
An error of type E_ERROR was caused in line 80 of the file
Hey @oliviaroach,
This is related to the new Jetpack release. Until a point release is available to fix this, you can access your WP Admin by adding ?calypsoify=0 to the end of the URL in your browser’s address bar.
You could also downgrade to the previous version of Jetpack. To do so, download the .zip file for version 9.1 from the dropdown at the bottom of this page. Then, navigate to WP Admin > Plugins, and deactivate and delete the version of Jetpack you have installed now. Then, go to Add New, and upload the entire .zip file you downloaded from this email.
A final option: if you’re able to log into your WP Admin and can add a plugin, you can use a plugin like Code Snippets to add the code I’ve linked below to your site:
add_filter( 'jetpack_tools_to_include', function( $tools ) {
$index = array_search(
'calypsoify/class.jetpack-calypsoify.php',
$tools
);
if ( $index ) {
unset( $tools[$index] );
}
return $tools;
} );
Note: This will be fixed in the next Jetpack release, so if you’d rather not do any of the above and just wait for the fix, you’re welcome to do so.
Please let us know if you have any other questions.
Best,
May I ask when the next Jetpack update is scheduled for?

@oliviaroach Jetpack 9.2.1 was released on December 10th. Can you try updating to that latest version and see if the issue persists? Please let us know how that works for you, and we can go from there!
Managed to connect Jetpack and my issue is resolved with the update. Thank you for the help!
Hey @oliviaroach, that’s super news.
I’m going to mark this thread as resolved now, but feel free to reach back out if you still need us.
Cheers!
