On a MacBook I have downloaded a WP multisite over SFTP using FileZilla. I have also exported copies of all the required databases. I have updated all `wp-config` files to match my local DB settings.

The problem I’m having is that I get a white screen on both front and back end. I can’t even see the login screen at `wp-login.php`

I’ve tried the following with no luck:

* matched my local PHP version to the live server version
* set `WP_DEBUG` to true
* added `WP_DEBUG_LOG` to `wp-config`
* added `WP_DEBUG_DISPLAY` to `wp-config`
* increased `memory_limit` from 128 to 512
* set `WP_CACHE` to false

There is nothing in `debug-log` or my local error log and there are no errors showing on the screen.

As I cannot access wp-admin, I have also tried the following with no luck:

* renamed the plugins folder
* removed the theme being used from the themes folder

Any help would be greatly appreciated
