Hi there!
Thanks for contacting us. Yes, The Helix3 framework as well as template is compatible with Joomla 4 and PHP 8 now. But not the Hope Template is compatible with PHP 8.x. yet, sorry about that.
No worries, we are working to bring higher PHP support for our products. But we are yet to decide about Helix 3-based templates further though.
Stay tuned. Thanks for your patience. Have a nice day!
Note: Temporary fix: I have removed the reina logo and mobile logo for now for single logo visibility.
Best Regards
