First of all, thanks for your plugin.
I know that this error has been resolved, but I have checked the other post and try to resolve and it has been impossible for me.
I just installed mailchimp in my wordpress 4.0. in the URL
https://www.webabordo.com/es/como-esta-el-panorama-digital-en-espana/
When I try to test and subscribe one email I always receive:
“Error: Oops. Something went wrong. Please try again later. .”
I check all that I have read in the forum. Change FNAME to not required, API key, create a list, a group, etc…. But I can not find a solution.
Please, what can be the solution?
Thanks beforehands
