Resolved Backup Manager xmlSchemaParse() failed

[MG11]

Hi all,

i have a Plesk 17.0.17 With Update #18 on Debian 7.11. A few days ago I wanted to check if the backups are working and when i click on Backup Manager i just get sent to the System Overview with this error:



Can someone help me please? I am pretty new to plesk and i am not sure where to start searching.

Try to find something useful regarding this error in backup logs

/usr/local/psa/PMM/logs/pmmcli.log
/usr/local/psa/PMM/logs/backup-<datetime>

Thanks for your reply.

on a side note i tried the "plesk repair installation" command, but it did not help.

In the pmmcli.log where some errors but i do not know what to do now. This error repeats:

Something wrong with python, libxml2-python system packages. Try to run

# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components

or reinstall backup manager in Plesk installer.

 

[MG11]

The first command does not help. The error still occures.

How do i reinstall the backup manager? I tried it with the web interface and the cli but i do not see a component "backup manager" or something related for reinstallation.

Try to do it with

# plesk installer --select-release-current --remove-component pmm
# plesk installer --select-release-current --install-component pmm

related python packages will be reinstalled.

I did it and some packages were reinstalled, but i still get the same error in the log.

Try to reinstall python, libxml2-python system packages. Contact Plesk Support Team if not help.

Hi this basically did it. After reinstalling the packages it worked.

Thank you!
