plugins are not being deleted completely

Hi, I have been trying to delete LiteSpeed cache plugin lately and it seems like I cant completely delete the plugin.

Even though the plugin does not exist in the plugins list. I have this message on each page of the WordPress admin panel. and each time I’m trying to update a post or a product or do some sort of action in this site it gives me this error.

Can NOT find LSCWP path for object cache initialization in /home/shopipop/domains/shopipopy.com/public_html/wp-content/object-cache.php

please help, Screenshot attached
