Hi,

I’m having problems with the migrationprocess, blank screen after activation of EE4.
I followed the migration steps from:
https://eventespresso.com/wiki/how-to-upgrade-event-espresso/

installed Lite version: 3.1.37.12.L

Have tried placing the below code in the wp-config.php but without result.
define( ‘WP_MEMORY_LIMIT’, ‘128M’ );
define( EE_MIGRATION_STEP_SIZE, 10 );

The testsite is a clone of the current website and placed it in a sub directory. The WordPress version is: 4.9.4 with a Site Origin Vantage theme installed.

Hi there,

Are you deactivating EE3 before activting EE4? You can’t have both version activated at the same time.

If you enable WP Debug on the testsite you should see whatever error is causing the whitescreen, to do that you set define( 'WP_DEBUG', true ); within your wp-config.php file.

Also, remove: define( EE_MIGRATION_STEP_SIZE, 10 );

That should be used if your getting fatals during the migration steps, you not even getting that far by the sounds of it, so leave that out for now as it slows down the migration process.
