TYPO3 Core

I have made a fresh installation into the subfolder 'test5'.
At first I did not set the write access to the temp folder.
When I got the error message for not writable typo3temp folder I did:
chmod -R 777 typo3temp
on the server and refreshed the 'Basic Configuration' from Install Tool.

Now I get the error messages.

----------------
typo3temp/pics/ directory does not exist
Full path: /var/www/vhosts/story-castle.net/httpdocs/test5/typo3temp/pics/
This folder is part of the typo3temp/ section. It needs to be writable, too.

This error should not occur as typo3temp/pics/ must always be accessible in the root of a TYPO3 website.

typo3temp/temp/ directory does not exist

Now I create them manually and set the write permissions.
v10154:/var/www/vhosts/story-castle.net/httpdocs/test5/typo3temp # mkdir pics temp llxml cs GB
v10154:/var/www/vhosts/story-castle.net/httpdocs/test5/typo3temp # cd ..
v10154:/var/www/vhosts/story-castle.net/httpdocs/test5 # chmod -R 777 typo3temp

Then I refresh the install tool again and still get the error messages however with wrong path names:
----------------------typo3temp/pics/ directory not writable
Full path: /var/www/vhosts/story-castle.net/httpdocs/test5/typo3temp/pics/4cab48fcc8d27667d204855ff5801c08
This folder is part of the typo3temp/ section. It needs to be writable, too.

Tried to write this file (with touch()) but didn't succeed.
The directory typo3temp/pics/ must be writable!

typo3temp/temp/ directory not writable
