Code appearing on live site even after deleting plugin

Hi, I believe there is code from this plugin showing outside the main content on our website. I was testing the plugin to see if it was what we wanted to use. However, I didn’t notice at the bottom left of the screen, there is the code showing live: [wprevpro_usetemplate tid=”1″]. I’ve already deactivated and deleted the plugin. How do I remove it? I didn’t realise we are not hosting our website either, so I don’t have direct access to the backend.
