I already posted this in the german forum but got only one answer so far, so I’ll try to get a solution here, too:
My SQL-Database grew quite big so I saved the piwik_archive_blob_xxxx_xx and piwik_numeric_xxxx_xx tables of the years 2009 and 2010 via dump and deleted the tables. Now the data is required again and I put the dump-Data back into the database. But sadly no page-requests, page-titles etc. are shown, just Information about countries, Browsertypes etc. When I created the dumps I used Piwik 1.7, now I’m using 1.8.2. A german piwik-user suggested to install 1.7 locally and insert the dumps into the local database. The installation worked fine and I inserted the 2009 dumps but the local Piwik system doesn’t even allow to select 2009 data to be shown. So, what els can i do? The data is needed quite urgently so any help is very much appreciated.
