Thanks for those links. I got it to work now from some info from there.
I just put one sentence in the body this time. I had the full body I intended to post copied, then as soon as it was posted, I just edited and pasted all the info.
Looks like there is no issue when you use the quick edit. The full edit feature will still give you the same error message, but it looks like you can bypass those errors just using the quick edit feature.
