The default position of the switches is on the right. You need to turn every switch once (to the left), but the switch in the flame riddle room has to be set back (after obtaining the chest). And in the top right where 3 switches close to each other the lowest also needs to be turned back after the other two are active.
It's always hard to say what is missing or what was messed up from pictures, since switches all interact with several rows of spikes. ^^" I think the switch  from the image where you stand on the grid should be to the left instead of right, but can't say for sure if that's all or not.
If needs be you can send me your save files from the www/save folder to Naughty-Netherpunch@web.de and I'll bring your character to the end of the dungeon. (I only need the file with the save slot number in which you want the problem to be solved).
