Three trailing slashes?

This is exactly the thing I was looking for – thrilled to have found it, but don’t seem to be able to make it work – yet.

Uploaded and activated the plugin, entered the live URL exactly as it’s written under WP General > Settings. After realizing images are not being served via Coral CDN, came back and saw a piece of code you provided, added it to my functions.php, with no result again. Except, when I now click on any of my images (as in: open in new tab), there are 3 trailing forward slashes behind the myurl.com part, then wp-content, then the rest.

My site is at https://vectorzine.com (and that is the live url I’ve entered both in the plugin settings and that piece of code in my functions.php. Hope you get a chance to take a look and let me know where am I messing things up (cause I’m sure that I am). Thanks!
