I’m thinking about setting up a CDN for my website, but I’m worried about breaking images, caching the wrong pages, or causing login/cart issues. What mistakes should beginners avoid?

AI Summary

Users warn beginners to avoid caching dynamic pages, ignoring cache purge settings, skipping SSL checks, and forgetting to test forms, logins, carts, and mobile pages after enabling a CDN.

The biggest mistake I see is caching everything without thinking. Login pages, checkout pages, carts, and account pages should be handled carefully, especially on WooCommerce or membership sites.

Make sure SSL is working properly after you connect the CDN. Mixed content issues can make a site look broken or insecure, especially if old image URLs still load over HTTP.

Do not enable every setting at once. Turn on the CDN, test the site, then add extra optimization features slowly. That way, if something breaks, you know what caused it.

If you run an online store, test the cart and checkout after setup. I had a caching rule create weird cart issues once, and it took hours to figure out.

People forget cache purging. After updating images, CSS, or pages, your CDN may still show the old version unless you clear the cache or set rules correctly.
