Updated to Android Studio 3.0. Getting a “Kotlin not configured” error

I first tried with invalidate cache/ restart option but it doesn’t help me.

When I updated Kotlin to 1.1.60 in project’s gradle file, problem is solved.

Also, use this in app’s gradle for stdlib

implementation "org.jetbrains.kotlin:kotlin-stdlib:1.1.60" 

instead of

implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.60"
