FTP user rights problem - user 10000

Hi everyone,

I'm facing a user rights problem in Contao.

When I'm creating a new Template (e.g. fe_page) Contao doesn't create it under my FTP-user, which I wrote into the localconfig properly, but under the user '10000'.
So when I'm trying to edit the template on the server within a code editor I can't save my changes, since the file was not created under my FTP-user but under the user '10000'.

Maybe anyone has faced this before?

I'm running Contao 3.1.5


Thanks in advance, Manuel

Please run the Contao Check. The tool should tell you whether you do have to configure the Safe Mode Hack (SMH) or not.
