Duplicate url

Hello to all,
i have a problem with EasyBlog on my Joomla 3.4.4 installation.
The problem is quite simple: when a user subscribe to blog the email sent contains the link to read more but the the domain is repeated twice.

For example a bad link is: http://www.psiconline.ithttp//www.psiconline.it/index.php?option=com_easyblog&view=entry&id=25&Itemid=510 but the correct link would be http://www.psiconline.it/index.php?option=com_easyblog&view=entry&id=25&Itemid=510 of course.

How is possible?

The url of site is http://www.psiconline.it

Thanks
