I recently upgraded our old OpenX installation to the latest Revive code. The upgrade process went fine (only error was workflow plugin which is normal per documentation). All my banners, users, campaigns, etc. still exist. But now, after the upgrade, I no longer see statistics on the statistics page. I see some for yesterday's date (when I made the upgrade), but none for the hours after the update nor any for today.
I've followed the steps here: https://documentation.revive-adserver.com/display/DOCS/No+Statistics
The plugin is installed and enabled (even reinstalled it to be sure), maintenance is running, but there are no entries for any of my `ox_data_bkt_*` tables. These are completely empty.
Our installation for serving promos runs on one server, the management UI runs on a separate server (sharing code via NFS) but they two servers connect to the same database.
