Base table or view not found error

I got the following error when I try to create a view based on block as the content type:

SQLSTATE[42S02]: Base table or view not found: 1146 Table '{database}.blocks' doesn't exist

See below for the export dump.

Could anyone provide some pointers?

Thank you in advance.
