I'm using the “Dovetail” theme from spectacu.la on a blog I'm launching. The url is http://blog.resto-in.com/
I don't know why but a horizontal line appeared right above each post title (it only happens when you're viewing the homepage, if you click on an article, it goes away).
I thought this was due to plugins (Yet Another Related Posts and Sociable) but even after disabling theme, the problem remains.
I've even uninstalled and reinstalled Worpdress.
Does someone have any idea where this might be coming from?
