Upgrade to 4.3.1 help

Thank you, spark problem solved.

Now i have the following problem: when i apply the manual changes for Kint:

app/Config/Kint.php has been updated for Kint 5.0.You need to replace:Kint\Renderer\Rendererwith Kint\Renderer\AbstractRendererRenderer::SORT_FULLwith AbstractRenderer::SORT_FULL

I receive this error when running spark:

Class 'Kint\Renderer\AbstractRenderer' not found

at SYSTEMPATH\Config\Factories.php:129
