All of my images from external sites are broken. I’ve tried from Photobucket, Flickr, and Imgur, but non of them are working. Has something gone wrong? Or is there an update I missed?
Check your description with this tool first - http://revaxarts-themes.com/envatitor/. Otherwise, Open a new ticket on support, They will help you to solve your problems. Cheers. 
Yea, I use Envatitor all the time, it works on there, just not when actually in use.
I’ll open a support ticket, thanks
