I am a subscriber currently building my infrastructure on Joomla 6. I am facing significant technical hurdles with the Unfold, Mednic, and Federal templates that require your expert guidance.

1. Fatal PHP 8.4 Conflicts On the Unfold and templates, the sites suffer a fatal error: Call to undefined method Joomla\Uri\Uri::getInstance() when running on PHP 8.4. I have had to downgrade to PHP 8.3 and enable the 'Backward Compatibility 6' bridge to keep the site functional.I have not tried on Federal yet
   • Question: Since Cassiopeia works natively on 8.4, when will these templates be updated to remove reliance on the deprecated getInstance() method?.
2. SP Page Builder URL Rewriting Failure While core Joomla Articles rewrite correctly, SP Page Builder Pro (Page Items) do not generate SEF URLs correctly on Unfold and Mednic. They either default to index.php or result in 404 errors when SEF is enabled.Again have not tested on Fedferal yet but probably going to be the same • Question: Is there an updated router for SP Page Builder specifically for Joomla 6 to handle SEF natively without custom menu item overrides?.
3. Template Specifics • Unfold: Crashes on PHP 8.4 despite meeting all documented technical requirements. • Mednic: Stable on PHP 8.3, but URL rewriting for Page Builder is non-functional. • Federal: An older template where I expect similar legacy code issues. Do you have a recommended migration patch?.

Note : I literally spent hours trying to sort out the URL rewriting and Litespeed problems I look forward to your specific technical solutions for these points. Best regards
