Among the family sites still with Smart Matches there is the one below that opens, but shows only the headings, nothing else, see screenshot below. Elsewhere you can read that there are 17 items to be matched. No other site has shown similar problems so far.
Thank you for writing and we do appreciate the patience you had over this issue.
I would like to give a brief explanation for the system:
The smart matches are generated when you make a change in your family tree and
publish them to your website The data will then be compared with approximately 24 million
other family trees at MyHeritage . Due to the fact that this takes some time it will take 5-7 days to collect the data, depending on the size of the tree.
The smart matching technology is very dynamic.
It happens that in this "intermediate period" webmasters make changes in their family trees and remove individual cards and even entire trees. The result is that you have received a message that you have a smart match, but the actual details of this match has been removed from our data base. The "clean up" of this data in the smart match data base takes longer to process and the result is an empty smart match.
I therefor advise you to continue to to edit your tree online and these empty smart matches will disappear in due time.
Please, let me know if this problem consists over the span of over a week.
