Genius!
It was indeed a plugin related issue – the moment I turned everything off the event-manager worked as promised.
The plugin causing trouble was: Sharebar
All these plugins seem to be safe:
- Easy Contact
- All in One SEO Pack
- Get The Image
- NextGEN Gallery
- Google XML Sitemaps
- Google Analytics for WordPress
- MailChimp
- Outbrain
- Disqus
- Easy Tynt
- Akismet
- Jetpack
Hope this helps…
