1. Create a new post. 2. Include an Image, set filter to All File types and select "/etc/hosts". 3. You get served with an weird error message box displacing a weird error message. 4. After this the Substack posts editor is broken. Heck, every time i access the Dashboard, it waits forever to build the page.
Did find this text while browsing the source for an error (see original ascii art: https://pastebin.com/iBDsuer7):
