PKP PLN Plugin ask for Archive_Tar PHP extension

I would like to refresh this. Please note, this is specific to Plesk:
Make sure open_basedir contains:

  • files_dir as given in config.inc.php
  • folder of OJS installation (e.g. httpsdocs)
  • PATH to actually working PEAR version, e.g. /opt/plesk/php/7.4/share/pear

Make sure include_dir contains:

  • PATH to actually working PEAR version, e.g. /opt/plesk/php/7.4/share/pear
  • set this PATH as the first in the list (!)

Check to set the current version of PHP (in this example php7.4) in .bash_profile

alias php='/opt/php74/bin/php'
export PATH=/opt/php74/bin:$PATH
