I have a multisite installation .Today I checked the blogs.dir folder and I surprised as it don't have any folders for sub-sites.
That is a fresh installation made three days ago.It has 2 sub-sites and their content are not there in blogs.dir
I also checked my other multisite Installations with the same WP 30.4 version .It has all the sub-sites folders in blogs.dir
Could any one help me with this issue? I don't know what happened to those files and if it could occur any trouble in future
