[Plugin: WP-FileManager] Doesn’t work

Hi,

I’m having some issues getting the plugin working. I followed all steps as said, but I get a ” (Missing trailing slash)” error. Whenever I try to create a new folder or upload a file, it says operation was successful – but the screen is not updated: https://www.ubuntu-pics.de/bild/7041/screenshot_100_044__OX8m1x.png

Or is the plugin simply outdated?
