It looks like you’re in safe mode (which disables all themes/plugins). Try refreshing the homepage - I suspect the message will still be there.
That theme is not the one linked in the OP here. So the best thing is probably to disable that and switch to this one instad.
Thanks - you are correct (-links vs -link is a fork). I had added an issue on the other github project page, but haven’t found any other place to flag it. I think I had tried the -link one and didn’t see what I expected, so replaced it with -links (which does exactly what I need, but with the deprecated code). Sorry for the misplaced comment.
