Sub theme does not save the settings.

Created on 16 March 2024, 4 months ago

Problem/Motivation

I have created a sub theme from Tara. It works fine on the frontend, but saving any setting that is not part of the Global Settings tab in the admin does not seem to work.

Steps to reproduce

create a folder in themes (e.g mytheme)
create a file mytheme/mytheme.info.yml
create a file mytheme/mytheme.libraries.yml
create a file mytheme/mytheme.theme

The content of the file 'mytheme.info.yml' is:

name: My Theme
type: theme
description: Theme for CRMIndex
core_version_requirement: ^8 || ^9 || ^10
# Defines the base theme
base theme: tara
# Defines libraries group in which we can add CSS/JS.
libraries:
  - mytheme/global-styling
# Regions, quote the names
regions:
  header_top: 'Header Top'
  site_branding: 'Site Branding'
  primary_menu: 'Primary menu'
  search_box: 'Full Page Search'
  page_top: 'Page top'
  page_bottom: 'Page bottom'
  highlighted: Highlighted
  breadcrumb: Breadcrumb
  content: Content
  content_top: 'Content Top'
  content_bottom: 'Content Bottom'
  content_home: 'Homepage Content'
  sidebar_first: 'Sidebar Left'
  sidebar_second: 'Sidebar Right'
  sidebar_sliding: 'Sliding Sidebar'
  footer_top: 'Footer Top'
  footer_first: 'Footer first'
  footer_second: 'Footer second'
  footer_third: 'Footer third'
  footer_fourth: 'Footer fourth'
  footer_bottom: 'Footer Bottom'
  copyright: 'Footer Copyright'
  cookie_text: 'Cookie Consent Message'
  hidden_blocks: 'Hidden Blocks'

The content of the file 'mytheme.libraries.yml' is:

global-styling:
  css:
    component:
      css/style.css: {}

The content of the file 'mytheme.theme' is:

<?php

/**
 * Implements hook_theme_suggestions_HOOK_alter for blocks.
 */
function mytheme_theme_suggestions_block_alter(&$suggestions, $variables) {
  // Load theme suggestions for blocks from parent theme.
  foreach ($suggestions as &$suggestion) {
    $suggestion = str_replace('mytheme_', 'tarapro_', $suggestion);
  }
}
