Email notivication not working (Easyblog 5.0.8)

Hi all,

after updateing to EasyBlog 5.0.8 the eMail notification isn't working anymore. I've installed a cron job (an the remote publishing is working well).

But the eMail Notification isn't working. After publishing a new blog post I see under "Mail Activities" a new entry for each receipient with the status "Item is currently not published". When I run the cronjob I get the following message, but the status of the item doesn't change.

{"email_import":{"status":200,"type":"info","message":"Email service interval is not up yet. Next service is at 24. Juni 2015"},"twitter_import":{"status":200,"type":"info","message":"No Twitter accounts associated on the site. Skipping this"},"scheduler_publish":{"status":200,"type":"info","message":"No scheduled posts to process currently."},"scheduler_unpublish":{"status":200,"type":"success","message":"Executed query to process posts to be unpublished."}}


When I configure "sending email while loading page (or how ever it is called in english)" and reload the page I get the notification "You must provide at least one recipient email address." for each Mail - the status changes to "Item is currently published" - but no eMail is send.

Any ideas?

Best regards...
