But I checked this sql ** 'SELECT value FROM settings WHERE key = “active_theme” ** in db, it returns casper. I am confused.

Any help will be appreciated.

Hey there @Dennis_Li :wave:. Can I ask if you’ve made any modifications to your install prior to this? Thanks :slightly_smiling_face:

Thanks for reply.

I just update the ghost-cli. Because I first use ghost update, it shows that

Message: You are about to migrate to Ghost 2.0. Your blog is not on the latest Ghost 1.0 version.
Help: Instead run “ghost update --v1”.

After that, I use ghost update again. And the error occurred.

Sorry I’ll rephrase, have you made changes to the code of your copy of Ghost?
