multisite sites list seen but “privacy error” when I try to open dashboard

Apologies if help could not access site – just moved the site and nameservers have now caught up.
Again – my apologies.

Hi everyone. I got a bit braver than usual and clicked through to the page linked.
Guess what – all gone….

all I have there is:

Shall check the others, but I suspect the hackers had a lot of fun wrecking this large site.
If that is the case then I will need remove the multi-sites and rebuild.

Sigh

Try asking your host for a backup, if you don’t have one. But it’s unlikely to have been a flaw in Multisite itself.

Hi Ipstenu
I agree it is most likely not a flaw with multi-site.
I did a backup (home dir and dbase) from last year (before the rats arrived). Still can’t get anything to show in the multi-site area.
The database has the post information but somehow the connection between post and database is not happening and I get a warning with the https crossed out in the url

Puzzled.

I have recently moved this site to new hosting and am getting emails regarding the renewal of the auto SSL certificate in Jan 2018.
I will ask new hosting about this “unsecure site” issue. I can see the security certificae applying to the main site, but unsure re multi-sites being covered.

I feel I need to re-state the problem, along with some new information.

I have a multi-site that I can only access the main site, of.
When I go to the Network Admin/Sites I can see all the subdomain sites but
if I click on “edit” I get a warning of an unsafe site.

If I click through the warrning I see just 4 lines:
Index of /

Same 4 line display applies when I click “view”

If I copy the site url in the site listing I get a page that makes sense
ie:
https://sweetblogspot.com/wp-admin/network/site-settings.php?id=17

This page is connected to the database, because when I changed the http to https in all the listings on the page, these changes were mirrored in the phpMyAdmin database.

I cannot work out why this subdomain does not display correctly. It seems completely unavailable
URL: nichemarketingreviews.sweetblogspot.com

Looking at the dbase post area, on selecting a post I see the “guid” listing of the post as http, and maybe I need to change this to https – be nice if there was some way to do such a change globally.

I would be most grateful for guidance here.

Site history:
Main site hacked, and since, repaired.
Site recently moved to new hosting.
Subdomain access problem was evident when on old hosting, and has not improved with the new hosting.

Plugins have been cleared of unwanted and bad, wordfence installed on main site.
