Hi,

I updated to c0c2634 today and now I can’t import or create a theme. Importing says **500 Error** and creating a new theme says **Internal Server Error**. There are no other details in the dialog. I have a test instance that is on b459a58 and I was able to import successfully there.

Here is the error from the logs:

> ActiveRecord::NotNullViolation (PG::NotNullViolation: ERROR: null value in column “key” violates not-null constraint  
> DETAIL: Failing row contains (7, Alternative Logos, 1, null, 2018-07-16 18:45:42.528877, 2018-07-16 18:45:42.528877, 0, f, f, null, 5).

Hi @sirideain

Can you do a rebuild and let me know if that fixes the problem?
