@DanielB86,
This is 4-month old thread!
Please start your own thread. That way you stand a good chance of getting full attention to your specific issue. Despite any similarity in symptoms, your issue is likely to be completely different because of possible differences in physical servers, accounts, hosts, plugins, theme, configurations, etc. Thus one problem, on one setup is not indicative of the functionality and reliability of an application as a whole. So, please review how and where to post in this support forum: http://codex.wordpress.org/Forum_Welcome#Where_To_Post
