 * I am using the latest version of Litespeed cache 7.6.2, but unfortunately I encountered
   an error on one page that blocks the site. Interestingly, other sites have the
   same version and work without any problems.

   wp-content/plugins/litespeed-cache/src/cloud.cls.php** on line **1421**

 * We implemented the aforementioned correction manually because it is the customer’s
   production site. It is good to know that the next version will solve the problem.
