PC has been chatting to me about this in chat earlier.
Site moved via Duplicator plugin, but same error was produced after 2 manual moves.
DNS is not yet switched so you have to edit hosts as follows in order to see error:
This page contains the following errors:
error on line 26 at column 8: Opening and ending tag mismatch: meta line 0 and head
Below is a rendering of the page up to the first error.
New host is on a vps.
Thank you for your assistance.
