[Solder] Creating Modpack -> Freeze

[Lordmau5]

Well, I set up everything correctly:

- The Database

- My host has PHP and migrated the databases

- The folders

The Repo_Location is set to "public/modpacks" folder and should search in there for the corresponding modpacks.

But when I enter a correct modpack and hit the "Create Modpack" button, I get moved to a whole white page... Not even a single text on it...

Also the Mod Library page is bugged and shows me, that "Class Symfony\Component\HttpFoundation\Cookie does not exist"... same with the "Manage Users" tab...

Help please...
