 * I’m using [Hyper Cache](https://wordpress.org/plugins/hyper-cache/), a lightweight
   PHP caching plugin, for a week now and probably I’ll stay with it.
 * Even with its 404-caching option enabled I didn’t observe a decrease of logged
   404s in your logger. Of course this is just an observation, not a proof in any
   way.
 * Maybe you find the time to definitively verify if Hyper Cache is compatible with
   404 Error Logger, and, if it’s true, to add it to the list of compatible caching
   plugins.
 * Just to get rid of the ugly warning … 😉
 * Thanks again for your very nice plugin!
 * Tom

 * Hi [@ecdltf](https://wordpress.org/support/users/ecdltf/),
 * It took a while but I’ve just released version 1.0.1 which fixes this. Note that
   there is a setting in Hyper Cache that controls whether or not it caches 404 
   results – this setting must be turned off in order for the errors to be logged.

 * Are you sure? As mentioned above, I observed it for a while with 404 caching 
   On and Off, and couldn’t tell a difference (concerning the number of logged 404s).
 * For example, at the moment 404 caching is turned on – and there is definitely
   a 404.html and 404.html.gz in the cache directory – and Error Logger is happily
   logging as always (134 entries).

 * I haven’t tested thoroughly, but from looking at the Hyper Cache code the plugin
   will only log a 404 the first time it is seen – subsequent requests for that 
   URL will be served by the cache.

 * Yes, you are right.
 * With 404-caching enabled, only 404s stemming from _bots_ get logged. In order
   to log all 404s, the do-not-cache-404 option definitely must be turned on.
 * I didn’t see the difference because 98% of my 404s come from bots…
 * Thanks.
 * Tom
