I am working on a trigger but trigger is not firing when i insert record, even I am not able to see any traces in debug logs...
 

I have been receiving an error and I am stuck on where to go to resolve this. the error is "Challenge Not yet complete... here's what's wrong: 
The Account record home page may not be activated."

I cant seem to figure out what to do! HELP
