thank you for your reply,
I installed your method, modified the theme’s functions.php file, restarted “Front End PM PRO, W3 Total Cache clear cache;
However, I still have to visit “https://www.abc.com/wp-json/front-end-pm/v1” and browse more than 50 pages in one second (I can use the Wordfence plugin to find traces of browsing).
I have no choice but to disable it and switch back to the 10.x version, which is normal now.
But there is a new problem. Some members stay at https://www.abc.com/account before changing the 10.x version. Just like before, visit once every minute: https://www.abc.com/wp- Json/front-end-pm/v1/notification, but I have changed back to version 10.x….
What should I do, thank you.
