I have created a custom theme,

    └── book
        ├── composer.json
        ├── media
        │   └── image.png
        ├── registration.php
        └── theme.xml

After that I choose my custom theme via admin, my frontend not load correctly.

I tried, static-content deploy, clear cache, and remove <m2>/var/* files

css are calling but theme.js and responsive.js is goes to 404.




enter image description here

Suggest me, How to fix this..

  • Please share your theme files.. For a suggestion,pub/static(exclude .htaccess) and **var/view_preprocessed delete

There are two solutions

Solution 1 -

You need to define parent in your theme.xml file, so the that responsive.js and theme.js file will access from the parent theme

theme.xml ( app/design/frontend/Thomson/Book/theme.xml )

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
   <title>Thomson Book</title> 
   <parent>Magento/blank</parent> <!-- the parent theme -->

Solution 2 -

You need to add both the files responsive.js and theme.js in your custom theme.

    └── book
        ├── composer.json
        ├── media
        │   └── image.png
        ├── registration.php
        └── theme.xml
        |-- web
  • But luma theme does not have that js. How is that working? Commented May 27, 2018 at 3:05
  • I have exactly same issue, luma theme does not have that js. Commented May 3, 2019 at 2:52
  • Hey I tried the second solution but not working. Commented Aug 26, 2019 at 13:45

My issue was that it was constantly loading theme.js from the parent theme instead of the child theme even with cache cleaning..

I solved it by manually removing the symlink from pub/static/[...]/theme.js and doing a static deploy + reloading the page.
