How many language packs are included into Plesk license by default

Question

• I cannot enable additional languages under Plesk Branding > Languages. The limit of languages has been reached (with only one selected).
• How many languages can I use in Plesk by default?

Answers

By default one language is provided with the Plesk license. Default language can be changed, please see instructions here. 

NOTE: If your license was purchased through a Plesk Partner/Reseller, check the ability to change default language with them

In case you need more languages in Plesk to be available to choose at the same time, additional language pack will be required.
