Thanks all for your help. I finally found the problem. The date format I had specified in Daily Notes plugin option contained an unpermitted character, to wit: a colon in the time display field, and there was no notification from Obsidian, it just didn’t do anything. Had I posted a screen print of the plugin options I had specified you guys would have caught it immediately. I’m very much a newbie with Obsidian and I’m still trying to figure out the concepts and methods. Thanks for your responses.
