Hi again,
I’m replying to my own post because I have find solution for thins problems.
First problem with ‘freezing’ homepage was solved by simply changing state of checkbox ‘Add scripts to footer’ under Settings tab on dashboard.
Second problem was solved by putting ‘no_translate’ class on hidden elements.
Plugin was trying to translate hidden content and just putting content of hidden element as raw html.
I hope that this has helped someone with similar problem.
Best regards.
