Hi Guys,
I installed the mailchimp integration add-on and activated however it is not showing me under the add-ons. I tried disabling few plug-ins and deleting and re-installing and deactivate/activate but still the same issue. Can you please advise if you have seen this issue before? Here is the below what is installed:

Name Event Espresso – MailChimp (EE4.4.5+)
Version 2.3.5.p
Description A MailChimp addon for Event Espresso. By Event Espresso.
Author Event Espresso
TextDomain eea-mailchimp
Title Event Espresso – MailChimp (EE4.4.5+)
AuthorName Event Espresso

Hi there,

Just to confirm, are you logged into the site as an admin?

If you go to Event Espresso -> Maintenance -> Reset/Delete Data.

Click on the ‘Reset Event Espresso Capabilities’ button only.

Does it show up in the menu then?

Hi Tony,

Yes, logged on as admin.

Tried the reset but nothing changed. Still I cannot see.

Looking at your site, the EE4 MailChimp add-on isn’t active in the list of addons for EE, can you double check the add-on has been activated on the site.

Is this a WordPress Multisite install?

It is single site.

Yes, it shows as active. I deactivated and activated again but it is the same:

I’ve not seen this issue before, but since your site has the third-party “eway” gateway add-on, I did some checking and found this line of code that appears to be causing problems:

remove_action('AHEE__EE_System__load_espresso_addons', [$this, __FUNCTION__]);

If you’re comfortable with making an edit to a PHP file, you can go into the eway plugin’s /includes/class.Plugin.php file and comment out the above line of code found on line 95 of that file. Once that edit is saved, you’ll find the MailChimp add-on listed under add-ons.

A better solution would be to do this instead:

Change line 43 of that same file to:
add_action('AHEE__EE_System__load_espresso_addons', [$this, 'registerEventEspresso'], 12);
and then on line 95:
remove_action('AHEE__EE_System__load_espresso_addons', [$this, __FUNCTION__], 12);

Hi Josh,

Before I make the above suggested changes in the .php, I wanted to try something else and it worked. This is what I have done:

– deactivate the mailchimp add-on and delete
– Add few other add-ons (table view, grid view, calendar, waitlist)
– add mailchimp add-on

now all is working. I did not need to play around with the .php file.

Thank you.

I’m glad you’ve found a solution.

I installed that that eWay Payment method locally and it looks like it only interferes with the MailChimp add-on when it and the Promotions add-on is installed, once you install any additional add-on’s it no longer causes the above issue.
