[SOLVED] Found 3 files that are missing from the remote storage, please run repair

Hello,

thank you for the detailed answer. I am an end-user and unfortunately I am not familiar with programming.
I am not perfect in English and I had a little trouble finding a solution.
I registered here - also for the translation tool - to give my contribution. But I think that it is not made very easy for beginners.
I would like to write a German tutorial that explains the installation with my two German server providers. How do I proceed in a useful way here? Is there a german wiki or forum anywhere?
