Emoncms on an shared Linux Server (1and1) could not creat feed

Hi,

I want to install emoncms v8 on my shared server at 1and1 (1&1). I read the SharedLinuxHostingInstall.md, created a folder "emoncms" within htdocs and a mysql database, unziped the files. So far no problems!
However, I found no way to creat a folder emocmsdata above htdocs! Not via FTP or SSH.
I decided to try emoncmsdata within emoncms. The htaccess file were modified by adding 

AddType x-mapp-php6 .php
AddHandler x-mapp-php6 .php
RewriteEngine on
RewriteBase /emoncms

and the settings.php by adding the db user etc. Additionally I changed the lines

'phpfiwa'=>array(
            'datadir'=>'/kunden/homepages/43/d4xxxxxxxx/htdocs/phpfiwa/'
        ),

'phpfina'=>array(
            'datadir'=>'/kunden/homepages/43/d4xxxxxxxx/htdocs/phpfina/'
        ),
'phptimeseries'=>array(
            'datadir'=>'/kunden/homepages/43/d4xxxxxxxx/htdocs/phptimeseries/'
        ),
'phptimestore'=>array(
            'datadir'=>'/kunden/homepages/43/d4xxxxxxxx/htdocs/phptimestore/'

       )

After adding the timezone at the index.php, I can generate an input.

But now my problem is, that I can't creat a feed! Error: feed could not be created, undefined!

I think the problem is the "wrong" path of the emoncmsdata. 
Could someone try to help me?

tbh
