No car details and not activated theme

PS. i thought that it’s maybe because i’ve turned off ‘compare cars’ plugin, so i wanted to activate it, but i can’t.

“Fatal error: Array and string offset access syntax with curly braces is no longer supported in /var/www/vhosts/rect.pl/dobreauto.rect.pl/wp-content/plugins/compare-cars/thumbmaker/class.Kama_Make_Thumb.php on line 186”

But I don’t need turn it on if it’s not necessary. 🙂

should i start new topics with:

1. There is also no chance to translate placeholders, adcvanded options button albo ‘find it now’ button in search form.
2. Also, there is a problem with placing slider revolution on main page (sometimes, i’ve checed on chrome).
3. there are no fields in car specification section in car edit / car add page
