Hey guys,

I have a form to import files (xml and csv and validate this).
But the upload don’t work. I get the following error:

Importing a file into the resource collection “persistent” failed: Could not copy the file from “FleischRVIn.xml,text/xml,/tmp/phptsSajM,0,1832” to temporary file “/var/www/Project/Data/Temporary/Development/TYPO3_Flow_ResourceImport_570de3e1a38a6”.

This is my Settings.yaml
