This should be no problem. Make sure that you assigned the right outputsource to the monitor out and that the output level of the monitor out is turned up.
Also make sure to activate the "monitor cab off" function in the output menu to switch off the cab simulation for the monitor out.
If you still do not get any sound i would check if the amp that you are using is working correctly.
Some amps do not activate the fx loop unless both sockets are plugged in. Insert any guitar cable into the Send (or even a spare, unsoldered 1/4" plug alone) and see what happens 
Hi guys,
I have the same problem with a Blackstar HT 40 !
Have you figured out how to make the monitor out work to use the speaker of an amp? Maybe it is an issue only with Blackstar amps?
Please help as I have to use it as monitor for my gig on saturday! Thanks
Have you already tried what has been suggested in the thread?
Matt, have you figured it out?
I have not, for the gig of tonight I had to find a back-up solution! A friend of mine gives me an active speaker.
pfffffff so frustrated!
let me know anyway.
Cheers

I answered in the other thread. I also looked up the manual of the Blackstar HT club 40. There doesn't seem to be any quirks with the loop according to the manual. If you follow my suggestions in the other thread and it still doesn't work I'd guess your Blackstar's loop is broken.
Yes Ingolf thanks, I had seen your messages in my thread.
As you could see I found a solution, so now I just wanted to tell it to MaFunk in case he hasn't found a solution yet.
MaFund, just plug any jack as viabcroce and Ingolf have suggested, but not in the 'send'; plug it in the 'input' of the amp. It worked in my case.
Cheers
Ohi! 
- Is it better to use balanced or unbalanced cables to connect kemper monitor out to effects loop return of combo am
The connection will be unbalanced anyway so you should use a TS cable.
Thanks!
