Owl Carousel deinstall? Fatal error php 7.1

Hello,

I use another carousel, so i dont need the owl carousel, but i dont see any installed owl carousel at the wordpress plugins. So how can i deinstall? Got i some problems if i delete the folder (wp-content/themes/arcane/addons/)wp-owl-carousel from the ftp?

The theme/plugins does not work on server with php 7.1 (7.1.6). I have downgraded my server to 7.0.20, so it works fine.

Why another carousel? No sort asc/desc > time/date, original-picture does not fit (resized/cutted), oppacity only in css, text on image not readable (no text-background, only in css possible)…

best regards,
Michael
