Just upgraded to 2.0.6 from 1.8. We are using WP 3.9. Any navigation in the admin screens now causes WP to prompt for our FTP credentials. If we enter them then we end up on the Calendar settings screen. Note that this FTP prompt occurs everywhere within the admin area and not just on the Calendar pages. If we deactivate the Calendar then the issue goes away.
What might be the cause of this and how do we fix?
