My environment:

  1. Magento 2.0.7
  2. Production mode
  3. Cache enabled

I cloned current Database that my store has been normaly working with:


and named it:


All DB details that changed are: database name, and user name. The rest (host, password) remained the same.

I change details in etc/env.php file by simply replacing appriopriate data. Then flush the cache. However, although the DB is cloned (= is exactly the same as the original one) the store it's not working. I'm getting error:

There has been an error processing your request Exception printing is disabled by default for security reasons. Error log record number: 455082819174


  1. How can I found out more about the error? Nothing is generated in var/log
  2. How can I fix the problem?
