-====== Managing Cache Tag Prefix Conflicts ======
+====== Managing Cache Tag Conflicts ======
 Cache Tag Prefix conflicts can pop up when you have multiple instances of the same web application with [[litespeed_wiki:cache#litespeed_cache_plugins_by_application|LSCache plugins]] enabled and using the same cache root (as in a WordPress site at ''/public_html/'' and another one at ''/public_html/wp2/'').
 **Note**: This is not relevant for a single multi-site WordPress install.
 ===== The Problem =====
-Of particular concern is the cache tag, which is the same across all instances of a particular app. In a single-site install of Wordpress, for example, it's always ''b1_''. The cache tag is used to group together pages from the app. As such, it is in control of which pages are purged from cache.

-In a situation where you might want to purge your entire Example Blog from cache, and you press that button, LSCache interprets the command as “purge everything with the cache tag  ''b1_''” and out goes your entire Example Blog cache //and your Example Store cache as well//, because it also has the ''b1_'' tag.

 ===== The Solution =====
-To differentiate one instance of the app from another, you can give each installation its own unique **Cache Tag Prefix**.
