Everyone I know has been having the same problem :/ And then the damned search bar...DevaintArt needs a server check right now before everyone gets too pissed off :/ (I've contacted the help desk and they're not doing anything -.-)
I'm glad I'm not the only one. It just says error. Like if just choose photography or traditional art, I'll get all the results, but I can't search for particular things. Maybe if everyone that is having the problem, puts in a support ticket, it will get fixed.
