I don't have the premium installer but poked around the downloadable free plugin and changed a few things to set it licensed but I can't tell if it matters or not. I saw somewhere that it limits to 2 sites, and so I tested by attaching 3 and that worked for me, and I ran backups. I am uninstalling this because it doesn't really help me - I already have backups scheduled and this "central" app has almost zero features or any value added in my opinion. Actually, I think rather than supply a file I will show what I did instead.
First I got the plugin from here
https://wordpress.org/plugins/updraftcentral/, and the current download link from there is
https://downloads.wordpress.org/plugin/updraftcentral.0.8.29.zip
In classes\licence-manager.php,
I changed this line:
Code:
private $no_licences_required = false;
to this:
Code:
private $no_licences_required = true;
In site-management.php,
I added this line, under the other two defines at the top:
Code:
define('UPDRAFTCENTRAL_NOADS_B');
and I also added this at the top of function is_premium_installed()
After these mods I followed directions, which is basically to make a new page on the site with the shortcode they tell you, then visit that page. Then on other different sites that have updraftplus I went to advanced settings and updraftcentral, make a key, pasted it at the central site and it worked to add it.
I don't know if these changes were all required, or if maybe this is insufficient, but it worked for me. Again, this does not appear to be a useful or quality plugin and I think that is why no one is bothering to post it at Babiato - I say this as a caveat so someone doesn't waste their time because they see this and think there is something to it - I just happened to be looking at updraft vs duplicator and was curious about this updraftcentral and that is the only reason I looked at it.
