Woohoo! Had to do a little bit of searching to figure out how to do that on my hosting provider, but it was set to off and turning it on did the trick!
Thanks for troubleshooting for me. Anxious to see the plugin develop more. I'll support with upvotes on every update post!
(I noticed that the body text preview just renders markdown as plain text. If a post opens with an image it makes for a messy preview as it shows the image code and url link as text. Any way for me to correct this or chances it'll change in a future version?)
