Hi, I have an average website running for a year and I need to switch it to multisite, but somehow I can't:
1. I turned off all plugins.
/* Multisite */ define( 'WP_ALLOW_MULTISITE', true );
3. but on the Network Setup page there is only:
Upozorn?ní: Please deactivate your plugins before enabling the Network feature. Once the network is created, you may reactivate your plugins.
How I can fix it?
