Problem by update my Translation

Hello,

i have download and upload the german .po and .mo files in german on my FTP (from https://wpgeodirectory.com/translate/projects), that’s work correctly. However, a few more translations have to be made.

I have read this Page: https://wpgeodirectory.com/docs/getting-translation-files/

I make corrections with Poedit and then upload the files, then the links of the homepage does not work.

I saw in the Video from GeoDirctory YouTube Channel (https://youtu.be/mocylaXgWvU), i must edit the wp-config.php, and edit define (‘WPLANG’, ”);
to define (‘WPLANG’, ‘de_DE’);

I have download wp-config.php from my FTP Server, but this Line is not in wp-config.php from WordPress. So I inserted the line, and unfortunately it still does not work.

Can u help me?

Best regards.
