Site entry not created and blank page

Hi all,

I finally come to this forum after having tried many ways to make my multisite work. Here is the symptoms :

– I successfully install a multisite version at the root of my domain, using a sub-folder approach
– The root website works perfectly well
– When I create a new website, the admin panel of this new website works and additional tables are created in my DB
– However, there is no additional line in the admin “mysites” menu, even though I can see a line for my new site if I go to the “sites” section of my root site.
– Furthermore, if I try to visualise this second site, I am served a blank page.

In order to make sure there was no additional noise, I deactivated all plugins, but it doesn’t change anything.

I don’t really know how to approach the debugging process and if you could give me a hand, it would be fantastic !

Thanks a lot in advance,

Benoit
