vsftp - 550 Failed to change directory

[latcarf]

I have been running an anonymous ftp for some time and all of a sudden any files recently added give a "550 Failed to change directory" when I or anyone else try to download them.

I just discovered this when someone sent me a file to place on my ftp then they tried to download it after. Files seem to be uploading fine and any files previously put out there seem to be downloading okay.

I have not opened the config file in some time, wasn't broke so there was no reason to fix it!

Anyone have an idea why this is happening?
