Plugin activation makes posts page blank

I’ve been using FBIA plugin for a while now(months) but recently(like 7 days ago) plugin is making a lot of problems.

If i have 3rd party option enabled(GA for example) i cannot make any change on website – i just get white page.

If i disabled 3rd party option then saving changes works normally, but any post becomes white page(on front page).

I have tried disabling all plugins(including theme must use ones) and i get same result, so i would guess it’s not other plugins fault.

The page I need help with: [log in to see the link]
