Blank page when viewing a discussion
I just downloaded the newest Vanilla and when I install it and create a new discussion, I get an empty page (the discussion is added). After that, when I click on any discussion to view it, I get an empty page, too.
I already tried reinstalling it, checked all the permissions, reuploaded all the files and tried a different version (one that I installed on the same server, worked perfectly)
