Every solution gives "Restricted function"
Example:
task "1000. A+B Problem"
I'm sending the simplest ever go program (without any import or function call):

package main
func main() {
}

(solution id 6393085)
And get "Restricted function an test 1":
6393085    Evgeny Sibil    1000. A+B Problem    Go 1.3    Restricted function    1

Now fixed. Thank you
