Resolved wrapper file empty / Permission denied in Plesk

[Fabrice Pajak]

Hi,
I was having trouble with Server Backup these 4 last days, and Plesk Onyx would not update packages or itself anymore.
After trying a manual update with SSH, I get
---s--x--- 1 root psaadm 23104 Oct 28 09:41 /usr/local/psa/admin/sbin/mod_wrapper
---s--x--- 1 root psaadm 0 Dec 13 10:32 /usr/local/psa/admin/sbin/wrapper

wrapper file is empty (0 byte).

Now in Plesk I have "Permission denied" errors in Plesk modules related to the system and servers:

For example: sysinfo failed: sh: /opt/psa/admin/bin/sysinfo: Permission denied

Impossible to update, manage servers, view server info ...

This is propably because the wrapper fil is empty and not working. Sounds like Plesk is corrupted.
My question: HOW CAN I REINSTALL PLESK CORE ? or re-install a correct wrapper file ?

Thank you for your help .

Fabrice

Solved by copying another wrapper file from another Plesk installation.
