It's possible that the problem is that updating PHP also updated PEAR::DB, and it bumped up to a version that doesn't get along with LibStats. Do you happen to have any record of the PEAR versions that were running on your server before the upgrade so that you can compare them against current versions? It might be possible to simply downgrade the dependency to restore previous functionality (though of course you then run the risk of running into some other incompatibility between an old version of the library and PHP 7... it's never easy!).
For what it's worth, users running very old versions of VuFind (from before it switched from PEAR::DB_DataObject to Zend\Db as its abstraction layer) occasionally complain about breaks after upgrading PHP, and the solution usually turns out to be "downgrade to a specific old version of PEAR::DB_DataObject." I'm not sure if this also applies to plain old PEAR::DB, but it's worth investigating if you have the option.

It appears that the database abstraction layer it uses, PEAR::DB, is not working correctly. Once instantiated, it's supposed to have methods like getOne() and getAll() that execute a SQL query and retrieve the results; but keeps complaining that these are undefined. I'm pretty sure this has something to do with the fact that the upgrade -- to Ubuntu 16.04.1 LTS -- installed PHP 7, up from 5.6. According to the PEAR web site, PEAR::DB is supposed to be compatible with PHP 7 despite being ancient and crufty, but it's not working. Anyone have any insight on how to get PEAR::DB to play nice in its new environment? Because the other option would be going in and rewriting all the database queries to use a more modern database abstraction layer. Probably PDO. That's certainly doable, but it'd be quite a pretty fair chunk of work, and in the meantime our reference and access services staff can't log their stats normally. Will Martin
