Fatal error: Uncaught Error: Undefined constant "GLOB_BRACE" ?

[rsend]

Hi, I tried running this on an embedded router (dd-wrt) to serve up photos locally. I correctly get a listing of iconified directory names if there are subdirectories, but I always get the below error as well. If I give it only a single root dir with images in it, I ONLY get this error. Any ideas?
