When you enter the location of a job, WP Job Manager will fetch data about this location from Google. This isn’t used by default, but some themes/add-ons use it to display jobs on maps etc.
By default, this geolocation will use the English version of placenames, so, for example, you may find users searching for jobs in “Sachsen” (German), and getting results for “Saxony” (English).
To specify the language to be used for geolocation, you can add the following code to your theme’s functions.php file, and replace the “en_GB” with the code for your chosen language:
You can find available language codes here.
