I'm having an issue with a customer where they have started having problems with `The requested URL returned error: 403` upon pressing the Verify button. Oddly it seems as though no one has done anything wrong or amiss with the configuration. Disabling the cache, reverting .htaccess, and so forth all yield no success. Apache DOES have byte-range support enabled for this server, yet I am wondering if something with WP or the plugin is screwing up and causing this problem.
Unfortunately neither the Apache error log nor the debug.log that I enabled with full verbosity give any specific information / details when I trigger this error. Is there a way to increase verbosity for logging for PowerPress that will allow me to pinpoint the real error that is going on here?
