Today, I downloaded the new version 2.0.0 of template Skylar_J4 and installed it on a local test site. When going to the template's settings, I immediately got the error 'Class "JFormHelper" not found'

I patched the issue in file tplhelper.php, only to run into the same issue in file subgroup.php. Subsequently, the same error in file textpx.php. After that, I gave up.

Obviously, the template has not been (completely) adapted to run under Joomla 6.

My test setup:

• Laragon 6.0 on Windows11
  
• Joomla 6.0.4
  
• PHP 8.4.11
  
• J6 compatibility plugin disabled
