You can use Auto Load Next Post in the language of your choice and suggest new translations using a community tool named GlotPress.
Once you have installed WordPress in your own language, Auto Load Next Post will automatically switch to your language if a translation file is available.
If you find untranslated strings, you can help by suggesting new translations here. All you need is a WordPress.org account to log in and start contributing!
GlotPress validators will have a look at your suggestions, and approve or change them if necessary. Once your translations have been approved, they will be shipped to everyone using WordPress in your language.
If you have more questions about Auto Load Next Post translations, do not hesitate to contact me!
Thanks a lot for helping!
