Why is my Magento frontend not displaying properly after an upgrade?

Common reasons your Magento 2 frontend may break post-upgrade:

• Theme incompatibility with the new Magento version.
• Outdated static content or cache not being cleared.
• Custom modules conflicting with layout or template files.
• Missing or misconfigured JavaScript and CSS files.

MagentoBrain will debug theme files, recompile code, and ensure proper static content deployment to resolve all UI/UX issues after an upgrade.
