What does a red checkmark on a folder mean?

On the hosting site for my domain they have created for me a symbolic link to a configuration file (that is in a system directory) of which I am the owner. I see a red checkmark on top of the folder containing that file. (How come I cannot get help from the program to tell me what that means?)

I can't see the symlink file in SmartFTP, even though I can see it in SSH AND file EditPlus FTP. I see that I am the file owner and have read-write permission to it.
