Today, April 10, 2019, we were approached by several clients who have discovered that on the sites managed by WordPress appeared some redirects they didn’t do . Our experts investigated the problem and came to the conclusion that the problem in the Related Posts plugin ( /wp-content/plugins/yuzo-related-post directory ). That information has been confirmed by the topic on the official WordPress site https://wordpress.org/support/topic/plugin-redirecting-to-weird-sites/
If you encounter a similar problem, we recommend the following steps:
1. Disable the Related Post plugin, at least until the security problem is fixed.
2. Clear the WP cache, if you used special plugins for caching
3. Update cms and plugins to the latest versions ( make backup copies before ).
If the problem persists, please contact our specialists for help.
