Hi WPMUDEV Team,
due to the reason, it is a german translated File, my defender assume is as different from original.
So I ignored it. See pic:
But I get every day the error Mail from Defender:
Scan of https://hubermanfred.de/ complete. 1 issues found.
/wp-config-sample.php This WordPress core file appears modified
For me it is good to be informed if someting goes wrong, but now, everyting is OK.
I dont need a error Mail.
Best regards from Bavaria
