Magento Theme – Theme Not Displaying on Front-End After Install

Did you disable or flush the cache?

According to you said, 'nothing happened', can you try:

input the 'default' in default field, and input the 'custom_theme' in template,skin and layout field.

Good luck.

==================Update following content=====================

Hi, I just download whole new free theme bluescale and make a sub theme, and edit the header.phtml file and it works.

Since you did not provide more detail about your problems, such as 'nothing happend' or your theme file structure, so I did it whole example for you.

And Magento's structure is based on a fall-back hierarchy, so I GUESS there are something you need check:

1. Does 'ultimo' folder has folder named 'default' to supporting your theme?

=================Latest Update======================

I just test the custom template on Ultimo theme(Ultimo_v1.3.2), it still working.

All I can say is your configurations for the theme setting seems all good so far.

So I am going to Keep guessing:

1. did you try remove var folder in the root path ?

2. did you try check the file permission ?

3. did you try a clean Magento and install the new custom sub theme. If new clean Magento working with custom sub theme, you may want to disable the extensions one by one to find out which extension causes theme problem.

if all of above nothing work, change the WAMP to XAMPP or keep googling.

Thank you @Alex! Your solution worked for me! I can see from the source that admin area is using my theme now.

Steps:

1. create a new theme in app/design/adminhtml/Vendor/Themename. In that directory, create a theme.xml:

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd"> <title>My Theme Tile</title> <parent>Magento/backend</parent> </theme>

And a registration.php:

<?php \Magento\Framework\Component\ComponentRegistrar::register( \Magento\Framework\Component\ComponentRegistrar::THEME, 'adminhtml/Vendor/Themename', __DIR__ );

2. Either create new module for deploying your theme, or use some existing module; either way, in your modules module.xml add the sequence xml element to make sure your theme gets loaded last.

<config> <module name="My_Custommodule" setup_version="2.0.0"> <sequence> <module name="Magento_Theme"/> </sequence> </module> </config>

and in your custom modules etc/di.xml add the fragment that specifies the admin theme to use: <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <type name="Magento\Theme\Model\View\Design"> <arguments> <argument name="themes" xsi:type="array"> <item name="adminhtml" xsi:type="string">Vendor/Themename</item> </argument> </arguments> </type> </config>

3. run setup:upgrade and voila! Check what theme is being used by viewing source: all css and js files should now be loaded from /pub/static/adminhtml/Vendor/Themename/[language]/....

However, all admin pages seems to be missing styles. I am in developer mode, and did a setup:static-content:deploy [languages] (with no errors) but that did not resolve the issue. I have had this same issue on the frontend as well, but cant remember how I fixed it.. do I need to copy js and css files from magento-backend module to make this work?

ISSUE RESOLVED: it appears I have run into this issue: Correct way to Update a Theme's Parent in Magento 2 where if I install my theme and then change the parent to something else in theme.xml, it will no be updated in the database and it wont take effect. I had initially put Magento/blank in the parent-element, and that obviously did not work at all, and changing it to Magento/backend later did not help either (as per the link above). So I went in the database and set the parent_id for my theme by hand. And just like that, everything works :)
