Why is my cache directory empty?

If your cache directory is empty, it could mean that Quick Cache isn't enabled (see Dashboard -> Quick Cache -> Enable/Disable) or that there is an error occurring behind the scenes that is preventing Quick Cache from operating normally.

If Quick Cache is running properly, then an empty cache directory could indicate that Quick Cache has not generated any cache files. Quick Cache will generate cache files when the plugin is active and a visitor visits your site while not logged in (unless you have Caching for Logged-In Users enabled--Pro version only).

An empty cache directory could also mean that all of the cache files passed their expiration date (see Dashboard -> Quick Cache -> Directory / Expiration Time) or that Quick Cache recently cleared the entire cache automatically.

There are a number of reasons why Quick Cache might clear the entire cache directory automatically:

• You upgraded Quick Cache
• You restored the Quick Cache default settings
• You changed the WordPress theme
• You changed navigation menus
• You changed Links (you may or may not have the Links SubPanel on your site)
• You made changes to terms, e.g., Categories or Tags

Quick Cache automatically clears the cache when these events take place because not doing so would likely yield unexpected results. For example, if you modified your navigation menu and Quick Cache didn't clear the entire cache, visitors would be served cache files that included the old menu. Or if you changed your WordPress theme and didn't clear the cache, the old cache files would include the markup for the old theme. And so on.

There is a feature request currently open for a new option that would allow disabling the automatic clearing of the cache. If you'd like to see that option added to Quick Cache, I recommend posting a comment on the feature request. (Posting a comment there will also ensure that you receive updates when that feature is added and released.)
