Magento 2.4 – How to Disable Page Builder

You should see this issue if you've upgraded to magento 2.3.5-p2. This issue comes up when you have more than one page builder elements on the same page. Mostly causes issue when you have a custom page builder element on page for your custom attribute.

To fix this issue, in your uiComponent add the following item nodes under wysiwyg config.

<item name="is_pagebuilder_enabled" xsi:type="boolean">true</item>
<item name="pagebuilder_button" xsi:type="boolean">true</item>

You can find full example on github issue page https://github.com/mirasvit/module-blog/issues/162

Note: This has been fixed in Magento 2.3.6 https://devdocs.magento.com/page-builder/docs/release-notes.html#133-for-magento-commerce-236

Yes, you can run Magento without virtual host. for this follow these steps

1. keep your magento root directory inside /var/www/html like this /var/www/html/your_magento_directory
2. then inside core_config_data define your url as localhost/your_magento_directory/pub OR 127.0.0.1/your_magento_directory/pub
3. then go to your browser and write same path like http://localhost/your_magento_directory/pub

Now check your Magento is running successfully.

Note: in older versions of Magento you don't need to hit pub folder just give path till Magento root directory and you Magento will be working fine. because in older version index.php file is in root directory and in later versions index.php file is inside pub folder.
