I am having the same issue. Text shows fine, but when I switch to the image option, I get nothing. I tried clering my cache but it did nothing.
This issue is affecting my website, and it is also affecting a friend’s site. Our different websites are both hosted by the same host company (urljet.com). I don’t know…. is it possible it could be a hosting issue?
Quick follow up… I spoke with another friend who has upgraded to 4.1.1, and he is experiencing this same issue too.
I am having the same issue too. Also, when I upload a photo in the “Insert Media” section, I get an “error” message now. very frustrating.
Here is a link to the page I posted today. No idea why the photos are saving so small. They should be about twice that size.
