White Screen when trying to add a list

I'm having the same problem.
Does anyone know how we could fix that problem?

Thanks in advance.

There a solution to fix it momentaneously.
Just download the dev version.

thanks for updating the issue, i've tried installing the dev release but i get the following error message

Archivers can only operate on local files: temporary://update-cache-4c43693b/mailchimp-7.x-2.x-dev.zip not supported

what does it mean?, how can i get around it

never mind, tried it again a 3rd time and installs ok, but issue still exists

Did you run update.php? Can you confirm you have libraries 7.x-2.0 or greater? After refreshing lists, does it show a list of the lists from your mailchimp account? What version of entity are you using?

apache log

PHP Fatal error: Class 'MCAPI' not found in /htdocs/sites/all/modules/mailchimp/includes/mailchimp.inc on line 3, referer: /admin/config/services/mailchimp/lists

re-installing and a clear cache fixed the problem for me

Glad to hear it josebc. The moving of the MCAPI class definitely caused some frustrations, but license compliance etc bla bla bla!
