Sending Emails from CiviCase results in Error

[sammyyyamazaki]

Hi!

I get a strange Error when trying to send an Email by clicking on the small email icon in the case role table.
When sending my Email I recieve this error:

#######################################
Sorry but we are not able to provide this at the moment.
We can't load the requested web page. This page requires cookies to be enabled in your browser settings. Please check this setting and enable cookies (if they are not enabled). Then try again. If this error persists, contact the site adminstrator for assistance.

Site Administrators: This error may indicate that users are accessing this page using a domain or URL other than the configured Base URL. EXAMPLE: Base URL is http://example.org, but some users are accessing the page via http://www.example.org or a domain alias like http://myotherexample.org.

Error type: Could not find a valid session key.

I have searched the forum but couldn't find my problem.

I have already emptied the cache and tried sending Mails via the "contact view" (which worked)

Does anyone have a solution for this?

Hmmm strange, this works fine on my install. Have you checked what the error message mentions - your cookies settings?
