Dear Dovy,
Thanks for your fast answer.
Unfortunately, I can’t start the website, even the admin-backend is not accessible. So, I already tried to exchange the Redux-Plugin-Folder with the latest version of the plugin (4.1.9), but the error still remains.
I use the Evolve theme (https://themeforest.net), which needs the RedoxFramework.
Do I have to make some parameter changes of additional file exchanges in order to get the latest version run?
Could you give me a short manual about a proper update to the latest RedoxFramework 4.9.1?
BR
Stefan
