 * Hi Guys,
 * I’m running Jetpack in Development Mode on the site shown below.
 * Since updating to Jetpack 6.9 from 6.8.1 the site’s Jetpack Carousel now generates
   the following error in Chrome Inspector when cycling through images:
 * “Failed to load resource: the server responded with a status of 400 … yada, yada”
 * Identical errors now occur on all of my sites set up the same way. I’m aware 
   that Dev Mode has some limited features, but these new errors are a bit alarming.
 * Any ideas what may be causing them?
 * Thanks.

 * Do the errors go away if you switch off “Speed up image load times” and “Enable
   Lazy Loading for images” at Jetpack > Settings in your site’s Dashboard?

 * No. Neither are enabled, never have been.

 * Thanks Jeremy.
 * It appears that you discovered that this bug occurs with “connected” (non Dev
   Mode) Jetpack sites as well.
 * Thanks again.
