Hello! I am having issues with functionality after updating my site’s theme. I deleted the plugin and the error message did go away, which tells me it is something with the w3 plugin. Once I reinstalled after deleting, the message came back. I really like the plugin and I use it often, so I would prefer to keep it on the website. I copy and pasted the entire error message below
Thanks!

Hello Alina,
Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website and I can see that the CDN is enabled in W3 Total Cache Performance>General settings, however, you have not selected any provider or configured the CDN.
Can you please disable the CDN in Performance>General settings and let me know if the problem persists?
Thanks!
