Fixing “Class browser not found” in the Evolution File Browser

A broken file browser can make the whole manager feel unstable, especially when image TVs or editor integrations depend on it. One failure mode is the fatal error:

Class 'browser' not found in manager/media/browser/mcpuk/browse.php

This usually points to an incomplete browser installation, missing include files, or a mismatch between the current manager code and the browser package that was copied into the project. Hosting moves and partial updates are common triggers.

The safe troubleshooting path is to compare the browser directory against a known-good version, check include order, and confirm that the class file expected by browse.php is still present where the manager thinks it is.

Manager media tools in Evolution CMS are tightly coupled enough that partial file drift can break them in non-obvious ways. When this error appears, think “broken package integrity” before you think “mysterious PHP bug”.
