Much more useful to post the answer to the question, even if you came to it by yourself, so that others in the same situation can use it

excellent, thanks

@ipalomo You can delete the plugin folder from wp-content/plugins via FTP, or you can access the database (take a backup before anything else), go to the wp_options table and find the row with option_name of active_plugins – delete everything in this row’s option_value – this will turn off all the plugins on the site, which will allow you to access /wp-admin again. There you can reactivate everything else and install the latest update for MailChimp for WordPress, which has fixed the issue.

Danny’s reply above outlines how to get the site back up:

If you’re still having the issue, please go into your /wp-content/plugins/ folder and delete or rename the mailchimp-for-wp directory to get your website back-up. You can then re-install the latest version again.

That needs to be done through FTP, or via your hosting control panel, if you have access

Do you see the error on the front-end of the site too?

PHP version is not handled within WordPress – it’s at the hosting level that you need to change this.

Thanks for the prompt response! That’s sorted it.

Yeah unfortunately we don’t host the client’s site, but will be making the recommendation to update to PHP 7.2.

Cheers!
