Zend framework: how to migrate a site

I'm trying to copy a site built on ZF from production to a localhost environment. All files and db contents were copied but I just get a blank screen. No errors, nothing

Changes made in config.ini I added an entry for development:production

general.host = "localhost:8888"
db.adapter = PDO_MYSQL
db.params.host = localhost:8888
db.params.username = bla
db.params.password = bla
db.params.dbname = db_name

bootstrap.php

$frontController->registerPlugin(new Initializer('development'));   

.htaccess contains a few basic directives but if I put some random stuff at the top I don't get Internal server errors so I don't think it even reaches the .htaccess stage.

Did I miss some kind of configuration somewhere?

EDIT:

I have code below in my bootstrap but still get a blank page. Very quickly, it barely loads at all

$frontController->registerPlugin(new Initializer('development'));    

$frontController->throwExceptions(true);

// Dispatch the request using the front controller. 
try {
    $frontController->dispatch();
}
catch (Exception开发者_如何学C $exception)
{
exit($exception->getMessage());

}

Try adding this line before running dispatch() on front controller object.

$frontController->throwExceptions(true);

On production systems throwing exceptions is almost always disabled, enabling it on dev could tell you more about the nature of the problem.

Yes, you probably missed some configuration.

Try setting display_errors=On in php.ini. You should be able to see what is going on.

Also, like suggested - try putting $frontController->throwExceptions(true) before calling dispatch().

Regarding the .htaccess file - you need to put the AllowOverride All (or anything valid, other than None) in your apache.conf/vhosts config.
