[Plugin: WP Super Cache] Conflicting instructions?

I have the same question. I didn’t understand if
define( 'WP_CACHE', true );
must be added to wp-config.php or if it must be added only in certain cimcumstances.

An exhaustive reply will be very appreciated. ??

Not really conflicting, the first instruction is part of the installation as the plugin *should* add the line back in.

If the line is there while you’re upgrading from wp-cache then strange things might happen for example.

When the plugin is installed, just make sure if that define() is in your wp-config.php in the right place.

Ok, donncha: now it’s clear!
Thanks for this plugin. ??
