Hi Guys we are having issues with Mailchimp List and adding users - plugins are all activated and subscriptions working from Module however when trying to add user to list we get:
1 Errors: Bad request (Your merge fields were invalid.) => min@gmtcj.com)
Our List in Mailchimp has following fields:
Email Address: EMAIL
First Name FNAME
Last Name LNAME
Date added (API) SIGNUPAPI
When I look at List in Joomla and look at merge fields I only see the Date added (API) field -
If I try to add a name field it says already exists in list?

Hi MrBean,

That's a weird one. It shouldn't be the case obviously and I don't see anything wrong with the merge fields setup. The Date Added (API) field is created automatically as an invisible field to keep a record when and if the user was added through Joomlamailer.

The email and name fields are not shown in the interface because they are mandatory, always exist and shouldn't be altered through Joomlamailer. So that's normal behaviour that you wouldn't see them.

Regarding the error, can you please edit this file on your server: administrator/components/com_joomailermailchimpintegration/libraries/Mailchimp/JoomlamailerMailchimp.php
Modify line 17 where is says public $debug = false;
to:
public $debug = true;

Then try again to add a user to the list and check the file
administrator/components/com_joomailermailchimpintegration/libraries/Mailchimp/mc_api.log
At the end it will show ".... Response:" and there will be the error message and details.
Let me know what it says in this line.

Set debug to false again right away as the log file grows quickly and might slow down your system after a while.

Hi MrBean,

Thanks for reporting this issue and providing details. I managed to reproduce it and it was indeed an issue with the date format of the SIGNUPAPI merge field. I have release a new version just now, which also includes a fix for this issue.
The new version is fully compatible with Joomla 5 and no longer requires the compatibility plugin. This means almost every single file had to be modified. If you come across anything that doesn't work or shows errors let me know!

Get the new version here: www.joomlamailer.com/downloads

Best regards,
Pete

Yes I updated all good backend and adding users to list worked but broke front end site with 500 error. I'm presuming because the subscribe module was on all pages. I've had to revert to the older 4.01 version to get the site to load?

Hi MrBean and thanks for reporting this. I found an issue with the signup module caused by the recent update. I also added layout improvements so the form renders nicely using bootstrap form layouts as well as form validation for URL and date fields to prevent API errors when submitting the form. Please upgrade to the latest version (4.1.1).

Best regards,
Pete
