First off, great job and thank you for this much needed plugin, Zefta. I downloaded and installed "Media File Manager Advanced" successfully. But, the files display as text only --- for example mypicture.jpg or koala.png. (The thumbs of the files do not display as shown in your description). I considered that it may be a server permission issue. But, the flies are already set at 755. Also, I deactivated all other plugins to double-check -- but this was equally unsuccessful. Can you help with a possible fix?
