Thanks for this. Did you find that this fixed the extension?
Having done these changes, I still saw errors in two places so I switched Smarty 3 off again.
There's a slim chance that it was my existing customisations that caused the problem.
If you can confirm whether or not it works with these changes in place, that would be useful.
I'm using it in WordPress and CiviCRM 5.69.2.
