Cannot use File Manager with cgroups service started

Symptoms

Cannot use File Manager with started cgroups service.

Different errors appear while opening File Manager:

move process 7788 to cgroup for user testuser1 failed 
move_to_cgroup(): pam_open_session() failed 6: Permission denied

OR

Unable to open the directory: Unable to find the file /var/www/vhosts/example.com/httpdocs/css at the specified location

OR

Internal error ;-P 
TypeError: Cannot read property 'show' of undefined
undefined

OR

Internal error ;-P 
TypeError: Cannot read property 'hide' of null
undefined

Cause

This is Plesk bug with ID #PPPM-6057. It will be fixed in future updates.

Resolution

As a workaround, set DefaultStartLimitBurst=999 in /etc/systemd/system.conf:

[before]
<...>
[Manager]
<...>
# DefaultStartLimitBurst=5
<...>

[after]
<...>
[Manager]
<...>
# DefaultStartLimitBurst=999
<...>

and reload systemctl daemon:

# systemctl daemon-reload

As another workaround, for each affected user create the file /etc/systemd/system/user-$userid.slice.d/51-StartLimit.conf which contains:

[Unit]
StartLimitBurst=999

    Sadly this isn't working for me, don't know if I'm doing something wrong. Any updates on this question? Thank you very much.

    After aplying latest plesk updates and rebooting the system, the trouble has gone. I undid the workaround changes, rebooted again and it's still working ok.
