Fuel\Core\Database_Exception [ 1129 ]: SQLSTATE[HY000] [1129] Host 'box386.bluehost.com' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'
I don't know how to fix this error. I tried running 'mysqladmin flush-hosts' in command line and it did not work. Is this because I am using phpmyadmin?
So you need to figure out where all these connection errors come from. If you try to connect to a database over the internet, chances are that is the cause.
I did check out the page that you listed before I posted an answer and I am still unable to get it to work from my command line as mysqladmin is not found.
