So the cache purge is compiled in.  It may need to be configured 
to work properly with Nginx-Helper plugin though, take a look at 
plugin docs.

I suspect the reason for small responses returned from cache (as 
your other messages indicate) is a special purge request which 
isn't handled cache purge module but passed back to php, and an 
error message returned is cached.

As already suggested, if you are not familiar with nginx 
configuration it might be good idea to just switch off the plugin.
