Hi David. Hope you're ok.
So, I have new host and upgraded to php8. Out of 7 Price Tapestry installations only 3 are still working. All the others go to a 404 page.
All are set up the same way, although PT might be different versions, not sure. All have Wordpress in root directory and PT in a sub-directory.
Me being me, I deleted one site completely, both WP and PT. Downloaded the latest version of PT, configured it and uploaded to sub-directory. Went to setup.php and all I get is a blank page.
