[Plugin: Q and A] Recurring 404 errors after disabling plugin

I had to disable the Q&A plugin due to a conflict with the L2G plugin (like2get).

However, since I turned off the FAQs I’m receiving numerous error messages. Here the text of the error:-

A user tried to go to https://www.domain.com/wp-content/plugins/q-and-a/q-and-a.css?ver=0.2.7 and received a 404 (page not found) error.

Please would you advise where the faulty code may be hidden, and what I need to do?

Thanks!
