Restoring the Internal Link List in TinyMCE for Evolution CMS

When the internal link list disappears from TinyMCE, editors lose one of the fastest ways to build correct document links. In practice this usually means the editor integration is partially broken rather than TinyMCE itself being unusable.

What Usually Breaks

• A manager-side connector or script fails to load.
• Permissions or paths changed during an update.
• One site instance was updated differently from another on the same hosting account.
• The editor still opens, but the resource list endpoint returns nothing.

How to Diagnose It

• Compare the broken site with a working site on the same server.
• Open browser developer tools and watch the network requests made when the link dialog opens.
• Check manager and PHP error logs for missing includes or permission errors.
• Confirm that the connector responsible for building the resource tree still exists and is readable.

Best Fix Strategy

Do not patch the editor blindly. First restore the manager integration that supplies the internal resource list. If two otherwise similar sites behave differently on the same hosting, compare file versions, editor configuration, and custom manager overrides line by line.

Once the endpoint is healthy again, the TinyMCE link dialog usually starts listing internal resources without any additional UI patching.
