We recently upgraded to DNN Community version 6, and we are now seeing this error message when attempting upload images via Cute Soft Insert Image (see below). I've checked the image folders, and they are nowhere near 100 MB in size. I saw an earlier thread on this topic that suggested increasing the size of several security policy settings in the default.config file -- we've done that and it makes no difference (see second image below). Have you got a fix for this problem? The previous thread did not offer anything else.
