I have a strange error that started happening this morning. Not sure what it is really causing, but I am getting Cron Daemon emails about it with the error:
Fatal error: Call to a member function getURLs() on a non-object in /home/websites/mysource_matrix/core/assets/system/cron/jobs/cron_job_refresh_cache/cron_job_refresh_cache.inc on line 101
I realized we moved around some assets and an old asset had a refresh cron job on it, when the asset was no longer in the system. This seems like it should have fixed the error, but the emails persist.
