why is google search page popping up on some sites?

there is a site i used to be able to goto with tor. i just updated to latest 5.02 and when i goto the site it brings up a "google search" page.

however, i can goto the site without tor or using vpn connection.

is this issue coming from the site or tor? that is, does the site detect tor and reroutes me to a google search page?

no one knows why Tor browser now redirects me to a Google search page when i visit a site. not all sites but one in particular? used not to happen until this last update.

i don't know if this is Tor or the website doing this.
