Drush cc: xmlrpc() error: (-32700) Parse error. Not well formed

That error means a XML-RPC calls returned a wrong reply, which could also happen when a XML-RPC call has been done for the wrong server.

In the specific case, it can happen because a PHP error/exception was thrown in apc_clear_cache(), or because $base_url might not be set correctly.
In the latter case, the -l/--uri option should be used for Drush. In the first case, 🐛 Undefined variable $apc_node in DrupalAPCCache::remoteFlush() Fixed should resolve this issue too.

Automatically closed - issue fixed for 2 weeks with no activity.
