seems the same question on GitHub.
Could you provide more details how to reproduce it?:
Where do you see this issue? How do you reproduce this issue? How did you install LiteMage?

Thanks for reply, i also replied on GitHub as well.
Actually, i have no idea of what happened, and didn't do anything as well.
This appears in my server's error_log, and basically i just installed it and it just happened. I didn't see anything from the website about this error so far.
I install followed the instruction here:

Everything seems work ok in the backend
