Hello
We recently migrated from EE3 to the latest EE4.
When we activated the EE4 Mailchimp plugin, EE4 went into maintenance mode and our website failed (white screen).
We deactivated the Mailchimp plugin and got the website back working. Hoping you can help troubleshoot this. We have not been able to find error messages/logs, but when EE4 went into maintenance mode there was a message that the database should be updated.
Regards, Joe

Hi there,
Event Espresso going into maintenance mode should not cause your site to fail.
Sounds like the reason EE is going into maintenance mode is the EE4 MailChimp add-on is trying to run its migration to pull in the EE3 data to the EE4 version.
Before you go any further, create a database back first, just to be safe.
Activate the EE4 MailChimp Add-on and go to Dashboard -> Event Espresso -> Maintenance.
You should see a page stating EE is in maintenance mode and asking you to run the migration, follow the on screen steps to run the migration and EE4 will pull over the EE3 MailChimp data.
If you don’t see those options please add a screenshot of what you do see so I can take a look.

Once complete EE should switch out of Maintenace mode.

Thanks Tony
It may have been related to a the mailchimp plugin working with a custom plugin we had for EE4 (plugin creating a new message type and with an integration with a membership plugin). We will investigate.

Ah, yeah that sounds plausible here, it will depend on the specifics of what that plugin is doing.

Yes, I will still be around.
Support will slow a little during the holidays as we all spend Christmas with our families but do I do keep an eye on the forums for critical issues.

Hi Tony
Just checking as I saw some previous support posts where there was a critical error in the mailchimp migration possibly related to the mailchimp API key? Wondering if there is something I should do/look out for with that before I try to activate the mailchimp plugn again?

Hi there,
There was an issue where multiple API calls to MailChimp would cause MailChimp to rate limit the response and return nothing, that was a while back and we made some changes to work around that but I’m not sure if that is what you are referring to.
Can you link me to one of the threads you saw?
