Hello,
Whenever I published, an error always prevented me to do so. The error message is like this
Internal Error
Invalid compiler output.
Object reference not set to an instance of an object.
Exception Details:

Before I got this error, what I did was copy and paste all of my screens, actions from my clone to my original project. And then I replaced all of clone's database core to my original's database core. After I fixed the errors, I tried to publish but this error always shown. I don't really understand what it said. Can someone help me in this matter? Thank you.
