The folders are in the same directory. It doesn't display any error.

Do you have access to your server's error logs?  Perhaps there's something there that's useful.  Production systems shouldn't output errors to the browser, but should still log to a file.

Usually issues with opendir are permission related, but it's hard to troubleshoot if there are no errors.

You might want to try whipping together a quick script that just tries to open a single file (like a text file) inside that gears folder, and output it, just so you can confirm that PHP is able to read files in that directory.
