Problems making a light cone

I’m trying to complete this tutorial:
Tutorial

But when I get to 4:48 inside the video, something went wrong. Once I have laid the texture on the cone, it has a strong black line on the perimeter, and the circle at the bottom. I can not delete these without gaps occurring in the cone, it does not happen in the video. What can I do wrong?

Turn off profiles in the style edge settings.

Very simple when you know it. Thank you so much for the tip to you both.

Men nu kan jeg ikke slette ringen i bunden af keglen uden at der opstår huller i keglen. Hvor i processen gør jeg noget forkert?

Hide those edges, don’t delete them.

You can’t delete the edge but you can hide it.
