Server 500 Error locks me out of wp-admin!

    My site had automatically updated WordPress to 4.9.1.2 yesterday evening – I tried installing the MailChimp Activity plugin (from a Zip) this morning. I was immediately dumped out of the page and was locked out of /wp-admin with a Server 500 Error – i.e. this plugin totally bricked the backend of my site.

    I resolved the issue by reaching the plugins directory via FTP and manually deleting this to restore normal service.

    Hi Tom,

    First of all, I’m very sorry to hear that this happened to you. I’d love to make up for it.

    – WordPress 4.9.1.2 is not a valid WP version, is that a typo perhaps?
    – Are you running PHP 5.3?

    Let me know please!

    Same just happened to me, as soon as I tried to activate the plugin. Had to log into cpanel through my host and delete the plugin to return things to normal.

    Dang, I’m sorry to hear that Denise. Q: which version of MailChimp for WordPress are you on?

    Ps. Thanks for not leaving a bad review straight away. I really appreciate that.

    Hi Danny, if it’s of help I’ve also got Mailchimp for WordPress Pro installed – Version 2.7.26.

    Same here. WP 4.4.1

    @danny: on WordPress 4.4.1

    Hi Denise, Tom & Tom,

    I just discovered the cause for this issue, it turns out that the plugin fails pretty badly when you’re running an older version of the MailChimp for WordPress plugin.

    The plugin requires at least MailChimp for WordPress version 3.0 to work. I’ve just added this to the plugin’s readme and pushed out an update so the plugin fails gracefully when this requirement is not met.

    I’m really sorry about this error, it’s my bad and I should have checked to see what the plugin would do when running older version of the core plugin. I promise it won’t happen again.

    PS. Version 3.0 is a HUGE improvement over version 2.x so I really recommend updating to it if you have a few minutes. Let me know if you need any help with that.

    Hope that helps. If not, let me know!
