I have installed Litespeed cache plugin. The plugin caches all the posts and pages perfectly.
However, all the category and tags are not not being cached and is being added to ignore list after crawling. I have enabled caching for categories and tags in the settings.
It returns a message “All Urls which returned no-cache tags will be added here, after the initial crawling”.
Without seeing the site it’s hard to tell what’s going on. It sounds like the plugin author should be able to help you though? Perhaps check with them?
