Hello @westerndeal,
Thanks for your answer.
Yes, i’m using Wordfence plugin, i read that post, i’m sure definitely is my security plugin, is there an equivalent of that “disable the user enumeration” option in Wordfence? Because i disabled the similar option: “Prevent discovery of usernames through ‘/?author=N’ scans, the oEmbed API, and the WordPress REST API”, however the issue persists.
Thanks in advance.
