 * Having Async Javascript breaks the current version of GTMetrix plugin. I do not
   no if this is realted but I also gets
 * “failed to check for updates because of the following error: cURL error 28: Operation
   timed out after 10001 milliseconds with 0 out of -1 bytes receive”

   But I also have Fast Velocity Minify enabled.
