I can't upload my texture pack for Minecraft?

I wanted to upload my specially created texture pack for Minecraft to a page this evening so that others could also marvel at it. Unfortunately, this page always says:

Missing mcmeta data: invalid resource pack

In my opinion, this means that the mcmeta file is not available.

Now this file is there, I can see it and you couldn't play the texture pack without it.

I don't expect it but can someone help me here?

It could be because of a wrong name or wrong file extension or they are not in the right folder, just try all of this otherwise simply write to the website.

For me, a special character in the TP name cut everything.

Maybe it's because.
