Synology DSM 5.2 | nextCloud 10.0.0

I used all versions of v10. Beta, RC, Final. On my Synology´s with DSM 5.2 and DSM 6.0.2 all v10 are running, but one DS makes problems.

But one DS with DSM 5.2 have a new installation of nextCloud and makes problems. On this DS v10 Beta and RC are running, but not Final. After installing the Final, I want to start it and get a blank page in the browser, nothing more. If I switch back to RC1, all is okay and running.

What is the difference or what is to implement for a running NC?

Its closed, because of complet new installation. Now it runs.
