Issue User share as owner of the domain files

[jojod]

One of my clients domains has the system user jordan but when the client or I go to the file manager we see the user "share" how do I re set the system user on the files ?
I have already tried without success

plesk repair fs

find /var/www/vhosts/example.com/httpdocs/ -type f -exec chown user_examplesacln {} \;

find /var/www/vhosts/example.com/httpdocs/ -type d -exec chown user_examplesacln {} \;

Here are the file permissions

Since I have this problem, the server's scheduled backups are showing this message again:
Not all the data from /var/www/vhosts/jordand.fr was backed up successfully:
conf: Cannot open: Permission denied
pd: Cannot open: Permission denied

I tried to restore the permissions but it did not change anything How to restore default permissions in the virtual host directory on Linux?
