Markdown in preview mode

Cannot see the markdown text in preview mode anymore, i get a blank page when i click preview I tried to reboot and deleted style sheet to no avail. I am running the last version of DT Server and Mac os. Thanks for your help

Per your last sentence: I guess there aren’t many who could help because probably no one else experiences the issues you have. An example would probably help or a screenshot.

Let me rephrase : 1. I open my md file in source mode everything is fine 2. I click preview or side-by-side and i get a blank page, i can only get the source document

its working now, i stopped versioning … and evrything back to normal …thank you
