I have a J6 site with both shaper helixultimate and Pitech templates. It was created from your Pitech Quickstart Pack.
When I go to System -> template Styles and choose shaper_helixultimate -> template options I get "Failed opening required '/home/ottawaoc/test2.ottawaoc.ca/layouts/chromes/sp_xhtml.php' (include_path='.:/opt/alt/php83/usr/share/pear:/opt/alt/php83/usr/share/php:/usr/share/pear:/usr/share/php')"

Is this normal or am I somehow missing something? Pitech is my default template but if I change to HelixUltimate as the default I still get the error. This does not seem correct?
