Title: admin-ajax.php cache Last modified: September 25, 2025 --- # admin-ajax.php cache * Resolved [breadf](https://wordpress.org/support/users/breadf/) * (@breadf) * [8 months ago](https://wordpress.org/support/topic/admin-ajax-php-cache-2/) * My site uses WPML. There is an issue with its currency switcher. WPML support said LS cached admin-ajax.php file. I am not sure where I can exclude file. Below is their reply: * > _We have found that the issue is caused by the configuration of the LS Cache > plugin, because disabling it solves the problem.

I will check with WPML if there is a way to expose “ajax action” in the url.
