[Plugin: Kirki Toolkit] and newest WP 4.3

Hello!

I figured out that the Kirki toolkit plugin was causing troubles after updating WP to 4.3, leaving the dashboard and the website just white.

Used FTP to enter the plugins and with try and error, I know the problem is caused by the Kirki toolkit not working on this newest WP.

Now what should I do?

Any suggestion on how to solve this? Or does someone know a solution?

I contacted the person who built the theme (theme needs Kirki to work properly) but they offer help up to version WP3… so not sure if this will be of any help.
