    Your mailjet-for-wordpress plugin seems to be the error.

    Access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/
    plugins/ and rename or delete the directory of mailjet-for-wordpress plugin.

    Next, report the issue to that plugin’s developers.

    There is a problem with the latest version of this plugin. I solved the problem by installing the old version. The version number I installed is 5.2.8.
    You can download it by selecting the version number from the bottom of this page.
    After disabling and deleting the mailjet plugin from the plugins page on your site, and installing the 5.2.8 you downloaded, the problem will be solved. Your data will not be deleted when you delete the add-on, so don’t worry.
