Thanks so much for that.

The issue for me is not necessarily the form itself, but what happens after someone presses submit. I needed to give them a message to say that they were going to get an email which they needed to look out for – and the best way to do that seemed to be by using the landing page. I can’t now remember – is it possible for the subscribe form to display a message on the page itself once it has been submitted?

That would be fantastic – thanks!

I meant to say that I have already donated for this plugin, but could definitely do so again if you were able to look at it!

Thanks so much – I thought it might be something to do with the fact that I didn’t have any groups set up. I’ve applied the workaround – but you also have to go into the MailChimp settings panel within WordPress and click ‘Update List’ before the error goes away in the signup form.

Look forward to the fix!

Thanks

I just started a new thread as I’m getting this same error – but this time it is occuring on line 1189 of mailchimp.php – and it occurs every time the form is used. The signup process works so it can’t be a connectivity issue.

WP 3.2.1
Mailchimp 1.2.5
