Hi experts,
I have a fresh installation of SS 2.4.5 on a virtual machine with Plesk.
Everything works fine, but I can't create a folder in the assets area.
I can upload files to the upload folder, but I can't create a new folder.
I get an error regarding mkdir.
What can I do?

TIA Stephan

If you've made sure that your /assets/ directory has sufficient rights, then this might be due to an issue in (a new version of) Plesk, where the php safemode and open_basedir are a bit too restrictive. If you are ons shared hosting, you might want to contact your hosting provider about that...

the rights are 777.
safe-Mode is switched off
and my vhost.conf says: php_admin_value open_basedir none

But still it is not working :(

what does the error say?

It says "Error creating folder"
And if i look at the firebug console it says "error at mkdir"

that's not much to go by... this is while your site's in dev mode?

Yes its in dev Mode

But the funny thing is, that I can upload images into the upload folder.
But I can't create a folder in the upload folder.

Here is the detailed error message:

ERROR [Warning]: mkdir() [<a href='function.mkdir'>function.mkdir</a>]: Unable to access /var/www/vhosts/xxxx/httpdocs/assets/Uploads/Neuer-Ordner/
IN POST /admin/assets/addfolder
Line 595 in /var/www/vhosts/xxxxx/httpdocs/cms/code/AssetAdmin.php

I believe that this is an important issue as there are many virtual servers out there running with plesk.
