BuddyPress in Your Language
Like WordPress, BuddyPress has the built in capability to be used in any language. The instructions below assume you have already configured WordPress in Your Language and Installing WordPress in Your Language.
Like WordPress, you don’t have to lift a finger to apply BuddyPress translations or translation updates. Most sites are now able to automatically apply these updates in the background. If your site is capable of one-click updates without entering FTP credentials, then your site should be able to automatically update translations.
Is your language missing?
BuddyPress translation packages are only updated if the translation is at 100% translated, if you do not see your language after updating your translations, please consider contributing to the the BuddyPress translation project, to get started see Translating WordPress and post any questions you have on the WordPress Polyglots blog.
Getting the language files
Go to https://translate.wordpress.org/projects/buddypress/ and select your preferred language e.g. Hungarian
Select ‘all current’ as ‘.po’ and click ‘export’ and save this file to a folder on your computer, do the same again this time selecting ‘.mo’
Using the language files
Rename each file of the files to
buddypress-plugin-hu.po to buddypress-hu_HU.po and
buddypress-plugin-hu.mo to buddypress-hu_HU.mo
Using FTP upload both the .po and .mo files to
/wp-content/languages/ of your WordPress instalation. If the
/wp-content/languages/ folder does not exist, create it.
