Hello there,

Is this a multisite installation? If so, Event Espresso doesn’t necessarily have Multisite support at this time. We are working on this. However, if this is a Multisite be sure not to network activate Event Espresso or any of the add-ons.

Hi Jonathan,

This is not a multisite installation.

Hi Nuno,

Has the database prefix for this site been changed recently?

You may need to look in the database in the wp_options table for the events_mailchimp_event_rel_tbl and events_mailchimp_attendee_rel_tbl options and make sure that the option_value for those match the database table prefix that your site is using.

Everything seems ok, but the prefix is sp_ but i have the 2 mailchimp related tables.

what can i do more to solve this?

Have you looked in the sp_options table for the specific MailChimp options Josh referred to in his post above?

Hi Chris,

My sp_options does not mention mailchimp options

Hi Nuno,

Your sp_options table will have many more pages of options that what is on the screenshot.

The quickest way to find those is to do a search within the sp_options table, use the LIKE % search operator, and enter mailchimp into the option_name field.
