Also, one of the main reasons I purchased UpdreaftPlus backup plugin was that it works with Multisite. However, after network activating the plugin, I see a message that tells me that there there is an issue….
UpdraftPlus warning: This is a WordPress multi-site (a.k.a. network) installation. WordPress Multisite is supported, with extra features, by UpdraftPlus Premium, or the Multisite add-on. Without upgrading, UpdraftPlus allows every blog admin who can modify plugin settings to back up (and hence access the data, including passwords, from) and restore (including with customised modifications, e.g. changed passwords) the entire network. (This applies to all WordPress backup plugins unless they have been explicitly coded for multisite compatibility).
Why am I getting this warning when UpdraftPlus is supposed to work with WP Multisite?
