OK, I haven’t figured out what caused this, but I have found a way around it. I ripped fog out by the roots and reinstalled. I opened the web page to create the database and when I migrated the old database to the new, I only migrated the tables relevant to the systems. That is, I deleted the SQL regarding the table ‘globalSettings’ and reset all the settings by hand on the ‘Fog Settings’ page. Now, everything is working.
