I upgraded, database has been upgraded too but now I get a similar message:
I did not remove any site before this error appeared. Anyway that’s curious.
Please tell me which table to review, to see what’s the “unexpected website” which
has been found : )
the patch didn’t solve my problem, so I was checking the table and I found the site which has been deleted was
ID#1, it was simply missing. So I rearranged the order from 1 up, checked the tracking scripts on all sites and now it works again.
But it appears to cause trouble, if page ID#1 is deleted while set as default page.
