I´ve transfered a single wordpress blog into a multisite (subdomain installation). At this single blog I had activated BackWPup. Now at my multisite I can´t activate BackWPUp any longer. The result is a white screen.
Apache Error Log says:
PHP Fatal error: Call to a member function remove_cap() on a non-object in /wp-content/plugins/backwpup/inc/class-install.php on line 59, referer: /wp-admin/network/plugins.php
How can I fix this error? Where are the settings of BackWPUp stored at the database?
