Wiping the cache on a multisite network results in the very next page view being cached incorrectly, because the zencache/cache/zc-blog-paths file is wiped also, and it's not rebuilt until after the next page view, and after the AdvancedCache class caches for the first time.

In that first page view (under the right conditions), this results in an invalid cache path being generated by buildCachePath(); i.e., it thinks the path is merely a sub-directory for the main blog instead of identifying it as a child blog token.

Bug exists in the updated branch we are working on for the next release only: wpsharks/comet-cache-pro#125, following improvements in the way cache paths are generated.

Steps to Reproduce

  • Setup MS network with sub-directory installation.
  • Setup two child blogs: child1 and child2.
  • Wipe the cache.
  • Without doing anything else, visit the front page of child1 or child2.
  • Check your zencache/cache directory.

Expected Behavior

That the child blog path is interpreted correctly.

Observed Behavior

The child blog is nested into the main site's directory incorrectly.

Wiping the cache now leaves behind the following files intentionally:

  • /zencache/cache/.htaccess
  • /zencache/cache/zc-advanced-cache
  • /zencache/cache/zc-blog-paths (MS network only)
  • /zencache/cache/zc-auto-cache.log (pro version only)
  • /zencache/cache/zc-auto-cache-archived-[DATE].log (pro version only)
  • ... anything else that is a regular file in the root of the zencache/cache directory.
