I hope you are well. There have been many changes since we last spoke!
I just moved my installation and get a 500 error when trying to access the /admin page. I think it may be due to the PHP 7 install and using an old PriceTapestry version. I searched the database tables and files but didn't see a version number. Where is the version number located? I'm sure it's something obvious that I have missed or forgotten.
