We published the article about Unexpected Magento 2 widget failures, and our immediate fix solution caused by libxml 2.15.1. Immediate reading is recommended to keep your e-commerce store stable.

In a word, our clients reported sudden issues on their Magento 2 sites even without making any updates on their side. Our team quickly identified the real cause and resolved the issue.

In the process of fixing, we discovered that this issue appears on servers running cPanel. We found that new cPanel builds of PHP 8.2 and 8.3 include libxml 2.15.1, which creates compatibility problems. As a result, this new libxml version affects Magento 2 Page Builder widgets using data-mage-init. The Page Builder content may fail to load. In the post, you will learn more details about how the widget attributes and broken HTML code look. Read it carefully.

To prevent issues caused by the new version of the libxml library, we released a new version of our core module, swissu/module-core 1.12.25. So, your main task is to update our core module.
