We'll create fresh WordPress site with XML-RPC De-whitespacer installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Uses PHP’s output buffering to buffer XML-RPC responses and strip superfluous whitespace.
Plugins, themes, and any other files executed during the WordPress load process can unintentionally emit whitespace,
such as by including a newline character after an explicit closing “?>” PHP tag instead of letting PHP auto-close the
file.
