Hosting CI4 on World4You Problem

I'v tried another free webhosting solution and this works without any problems just by moving the app/system/writeable paths and adapting the baseUrl parameter.

Then, I also tried to transfer this working setup to W4Y and changing the baseURL but it still gives me a blank page...
So I assume there is something wrong with Web-Hosting Settings of W4Y. If I get it to run I will post the solution but so far I did not manage to run it on a manages web host on W4Y.
