Theme development

Hi All,

I have been banging my head against a wall for 2 days trying to solve this. 

I have a local apache lamp stack using PHP 7.4.3 with apache and virtual hosting turned on.

The site that I am trying to turn twig tweak on with is a Drupal 8.9.13 site.  Its essentially a migration from Drupal 7 which I am trying to upgrade to D8.  I have gone about the usual things: 

Hello everyone,

Hi Forum

We are getting an error message when trying to create our own theme.

Please assist if possible.

The error message is below:

Error message

Warning: Invalid argument supplied for foreach() in Drupal\Core\Extension\ThemeHandler->addTheme() (line 125 of core/lib/Drupal/Core/Extension/ThemeHandler.php).

Dear Knowings,

I'd like to integrate a SVG-Image with inline Javascript to a node. The image is a map. When I hover a region of it, an explaining picture is shown. When I leave the region, the picture is unvisible. Therefor I need the script. It's generated in Inkscape with the function "plugins|internet|javascript|add attribute".

It's not the problem to insert the SVG with <svg> tag. I manged it with the module "svg image". So I am able to create a media SVG and insert it in the node as media. But the script-code is commented out. How can I prevent that?
