During the installation it worked OK, but once the installation finished, there are problems:
When I click the Sugarchimp module in the top menu bar, it fails and opens a window with the following message:
There was an error processing your request, please try again at a later time.
And at the bottom of the window there is another message:
If this error persists, please have your administrator disable Ajax for this module
I've enabled the connectors, but the Mailchimp icon does not appear on the Contact or Lead page
