Clean install 1.7.6 wont work


I want to upgrade my Xibo server from 1.7.5 to 1.7.6.
But when i download and install the files i have a white screen.

To be shure i made a new subfolder and uploaded all files like a clean install
But a white screen again.

It seems there is a problem with the download of 1.7.6.
Can anyone confirm this to me?

On the same server 1.7.5 runs perfectly

It should work just fine, please follow the instructions from here:

I tried again, but again a white screen.
Where can i download 1.7.5?
Then i can check if that version is working on the install

both should work just fine.

mmm but both wont show up the install pages

any other advice to solve this problem?
