Pasting text and images on ftp

when i paste txt or image data as a new file on an ftp folder i get this error message:

as far as i remember that problem existed before and got fixed but i still get this message.
Is there something that i must change in the settings?

Make sure you're using the latest version.

oh, i didnt reboot for quite a while. thats why i had an old version. now it works, thanks.
