Incorrect effects are displayed
Not sure what I am looking at. 
What is the problem, what should it look like and what does it look like now?
Is this something that used to work but has since broken when you upgraded Unity versions? If so what version did you come from and what version did you go to?
Try adding a valid material to the Renderer section of your particle system if you are referring to the purple quad.
Check the material is using a good and working shader if a material is present.
In future try to be more clear about your issues. You left these two replies to just vaguely guess.
