There are two ways to obtain default Plesk LP source files:
To take the LP sources from a Plesk instance:
std_lp.tar.gz archive downloaded with this Localization Kit to the server where the required version of Plesk is installed, and unpack the archive.get_orig_locale utility with power user privileges.For example, when logged in as root:
[root@localhost std]# ./get_orig_locale.sh
The utility creates directory orig_locale.en-US/ in your current directory, and copies the default LP's sources from Plesk directories to it.
