Reactivating WordPress Jetpack plugin throws an error

Question

I am getting the following error when trying to re-activate Jetpack plugin:

Invalid request, please go back and try again.

Error Code:invalid_client

Error Message: Unknown client_id.

Answer 1

This solution worked for me:

1. Deactivate and Delete Jetpack plugin
2. Go to your PHPMyAdmin
3. Run the SQL Query : SELECT * FROM `wp_options` WHERE `option_name` LIKE '%jetpack_%'
4. Delete the items that start with the option_name jetpack_
5. Download and Install Jetpack.

You should now be able to connect JetPack without any errors.

Answer 2

Be sure to sign in to your Wordpress.com account before connecting jetpack to wordpress. Doing so resolved this issue for me.
