WP Bakery Issue

I have been having problems using visual composer today. First when I try to use appearance > customise – the customisation page doesn’t display my sites colour scheme correctly and doesnt show saved/published edits. I deactivated WP Bakery to attempt to fix the problem but the reinstall from highend repositorykeeps “failing” Consequently live site https://cabo tdecorating.co.uk/ is full of errors. Can you help me reinstall the plugin?
