Since support seems to be on a roll lately, I've got a good one that I've been trying to track down!
Every few http requests to my site sees about a 10 second delay in the page fully rendering. When I inspect the page and look at the console, whenever the delay occurs, I see the following error:
"Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check
http://xhr.spec.whatwg.org/."
And it stops attempting to load 16 POSTS using the SEND command in this ES JS file. Any ideas as to what it's trying to do? It is always this itemid #126...
