Agree, but since current one was changed a lot, including hardcoding things in templates, I think it will be very hard to copy all the settings to a new one. I’m really only a few weeks working on WP and don’t know how to switch to totally new theme and keep my settings.

I assume it’s all because I run very old theme (Choices by https://www.kriesi.at/ ). Also the previous guy, who worked on this site did a lot hardcoding etc. Which doesn’t make upgrading easier..

Well, I did this but with no success..

I actually found a solution, but it’s really only a patch, to get my site to work somehow:
1)
downgrade jQuery version – changed in /wp-includes/script-loader.php from local jquery.js (ver 1.11.1) to //ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js, the one that was before.

2)
found and fixed (after like 4hrs of debugging) a coding error in my old theme
