We have just recently enabled Litespeed cache on our server We are using wordpress and a plugin called wishlist member on one of our sites and using a 1 click upgrade using their api. We are now getting an error "no auth lock to open" from the wishlist upgrade plugin. Essentially, it is a conflict with caching of any sort. The solution is to exclude all urls that include /wlmapi/2.0/ http://docs.happyplugins.com/docume...-error#Wishlist_1-Click_Registration_Solution I have Litespeed Cache Wordpress Plugin installed and there is an option Do No Cache Rules, however, there are no instructions on how to submit partial urls or regular expressions. I also have the Litespeed cache plugin installed in WHM and can access litespeed web server from there. Any help would be appreciated.
