Cause
Plesk bug PPPM-9978 (PPP-40448) which is already fixed in the upcoming major Plesk version.
For the current Plesk versions, the bug is planned to be fixed in future product updates.
Resolution
The upcoming major Plesk version is currently in the testing release tier and is not recommended for using in production.
Until the bug is fixed in the current Plesk versions, use the workaround depending on the operating system installed on the server:
-
Connect to the server using SSH.
-
Back up the original file:
# cp -a /usr/local/psa/handlers/hooks/dk_sign{,.bak}
-
Download the archive with the patched file and unpack it:
# wget https://support.plesk.com/hc/en-us/article_attachments/360029725134/dk_sign.COS7.tar.gz
# tar -xzvf dk_sign.COS7.tar.gz
-
Replace the original file with the patched one:
# mv -f dk_sign /usr/local/psa/handlers/hooks/dk_sign
-
Connect to the server using SSH.
-
Back up the original file:
# cp -a /usr/local/psa/handlers/hooks/dk_sign{,.bak}
-
Download the archive with the patched file and unpack it:
# wget https://support.plesk.com/hc/en-us/article_attachments/360030544733/dk_sign.Ubt16_04.tar.gz
# tar -xzvf dk_sign.Ubt16_04.tar.gz

Replace the original file with the patched one:
# mv -f dk_sign /usr/local/psa/handlers/hooks/dk_sign

Hello @Paulo,
Thank you for the provided information. I have double-checked the required permissions, 644 as you have is ok.
The case requires deeper investigation. I would suggest submitting a request for Plesk Support.
Hello @Paulo,
Let me correct the previous answer.
The attached fix is for CentOS, that's why it does not work on your system.
In a few hours, this information will be added to this article + we will add the fix that will suit you.
Hello @Ivan,
Thanks for your help. I will wait the fix for Ubuntu 16 :)
Thanks
