New WordPress 3.5.2 multisite (subdirectory) install is missing a slash when creating new blogs.
WordPress is installed to server like: http://blogs.domain.com
When a new user registers, the conformation email has the URL for their blog like: http://blogs.domain.comnewuser (missing the / between the domain and blog name).
From Network Admin, I can edit the site, adding a / to either the end of the Domain field or the begining of the Path field and the site can be accessed: http://blogs.domain.com/newuser
I'm guessing there is something missing or incorrect in my wp-config.php file. Any ideas on what could fix this?
