Folders not opening

Yes i have the same issue. When I click on a folder it opens for a second and then immediately closes again. The folders are inaccessible now. I am using the Pro version. Looking forward for a solution.

Thanks so much, after reverting Elementor it works again! Now waiting for the developer to provide an update for the lastest version of Elementor.

In my case, environment:
WP File Manager Version 8.0.4
Elementor Version 4.1.1
WordPress 6.9.4
PHP 8.4

There appears to be a conflict between WP File Manager and recent versions of Elementor.

Recent Elementor releases include a new AI Feature “Angie”, which sends a postMessage() event with a message type of sdk-angie-ready-ping. The message payload is sent as a JavaScript object rather than a JSON string.

WP File Manager’s elFinder.js registers a message event listener:

  jQuery(window).on('message.' + namespace, function(e) {
    var res = e.originalEvent || null,
	  obj, data;
    ...
  });

The handler then attempts to parse all message payloads as JSON:

obj = JSON.parse(res.data);

When Elementor’s sdk-angie-ready-ping message is received, res.data is already an object.
As a result, elFinder.js JSON.parse() throws an exception:
SyntaxError: “[object Object]” is not valid JSON at JSON.parse
because JSON.parse() expects a JSON string, not a JavaScript object.

After this exception occurs, the WP File Manager UI fails to function correctly as described in this post.

No related errors are logged to:
Browser console
WordPress debug log
PHP error log

The only visible indication is the JavaScript exception, which I identified by stepping through the code with the browser debugger and observing the try/catch block in the elFinder.js listener failing.

I have patched this code locally to handle both JSON strings and object payloads before calling JSON.parse(), and after doing so the issue no longer occurs in my environment.
For example:

// Handle both JSON strings and objects
if (typeof res.data === 'string') {
	obj = JSON.parse(res.data);
} else if (res.data && typeof res.data === 'object') {
	obj = res.data;
} else {
	return;  // Ignore unsupported message types?
}
//obj = JSON.parse(res.data);  // Incorrectly assumes string but could be object, number, array, etc.

Disclaimer: This is not claimed to be any type fix or proper handling, only what I have observed in testing. Any proper fix should be made officially and in the plugin.

I appreciate that this may not be the only cause of the reported issue, but it appears to be a reproducible compatibility problem in my environment.

Could the plugin developers please review this and confirm whether elFinder.js should support non-string postMessage() payloads?

Thank you, Erik
