Drupal 8.x

I'm running a new computer and struggling to implement a custom Drupal 8 theme (No base theme). Using MAMPPRO 4.0.1 when I create the theme folder under the themes directory, create the *.info.yml, create the *.libraries.yml. all produce these two errors-

Hi!

I'm having difficulty updating my current Drupal version 8.6.4 to 8.6.7 using composer.

composer update drupal/core --with-dependencies

I get this error message:

On my Drupal 8 site, I created pages with a Leaflet card that uses open street map data.

When I go to google search console, it tells me that the following links are blocked "Pages with blocked resources" :

- https://a.tile.openstreetmap.fr

- https://b.tile.openstreetmap.fr

What should I do ?

Hi All!

I made a views, where I listed manufacturers images and , names. When I click this image or name, loading the manufacturer page, with production categories.

The url is a node title. Eg. /productions/manufacturer/category/production.

This page is hungarian language, with hungarian characters. So the url: /termekek/Viastein térburkolat/Viastein térkő/Vieto mistro térkő

I want to convert the node title to url format, so I can make a full url: /termekek/viastein-terburkolat/viastein-terko/vieto-mistro-terko. I can't found solution this problem.
