Try deactivating all plugins and check to see if this resolves the problem. If it does, activate the plugins one by one – checking the post after each re-activation – until you find the problematic plugin(s). If that still doesn’t work, try switching to the default theme in case the problem is theme-related.

Incredible! That worked, after deactivating all plugins, magically everything was working fine! I think that the NextGenGallery was the problematic plugin, but I’m not really sure… anyway thanks
