Title: “(MISSING)” in urls Last modified: February 7, 2019 --- # “(MISSING)” in urls * [jeuansk](https://wordpress.org/support/users/jeuansk/) * (@jeuansk) * [7 years, 4 months ago](https://wordpress.org/support/topic/missing-in-urls/) * Hi, I was wondering if, by any chance, the WordFence plugin ever replaces characters in a user’s requested url with “MISSING” (maybe to protect against XSS)? * I ask because recently in the WordFence live traffic logs, I’ve noticed a few bots visit this url: * /login/?redirect=http%!A(MISSING)%!F(MISSING)%!F(MISSING)ourdomain.org%!F(MISSING) wp-login.php * The “normal” version of that url, the one that humans and most bots hit is: / login/?redirect=https%3A%2F%2Fourdomain.org%2F * Is the “MISSING” replacing something else, or are the bots really trying to visit a url with “MISSING” in the string??? * And, maybe it’s a coincidence, but our site has briefly gone down on two occasions within a few minutes of being hit by the bots visiting the url with “(MISSING)” in it, and I’m trying to figure out what’s going on. * Thanks!
