Cloudflare cache slows down site

Hi there,

Whenever I have the Cloudflare caching system enabled, my site is incredibly slow. Pages display a white screen and take minutes to load any content and when they do the font is incorrect.

If I have development mode enabled (which I believe stops the use of the cache), the website loads very fast.

Here are my settings:
Caching Level: Standard
Browser Cache TTL: 1 hour
Always Online: Enabled
I also have all options in the speed optimisation page enabled (the free ones).

What could be the problem?


Are you still facing this issue? If so, would you share your domain name? Also, please visit your site with Dev Tools open (F12) and check the Network and Console tabs for possible errors, they normally give good hints to start an investigation.

Thanks for your response.
Yes I am. The site is killa-media .com
The menu bar also often has issues due to this.
I don’t understand the errors, but I think the cache is breaking the js and or css.
Any further advice?


Do you have some special settings on your domain? Such as third-party DNS, some other proxy service? I ask because visiting your site I got a few 403s but when I open these files on a separate tab I see a 1000 error that says they are pointing to a Cloudflare IP address (as opposed to your hosting provider’s).

You can try for yourself with this URL:

The strange thing is hat DNS should affect all your site, not just a couple files. Check your Cloudflare DNS tab and bring in more details, luckily someone else with better knowledge of DNS may help you sort things out.

As far as I know, there aren’t any special settings.
What should I be looking for?

The 1000 error is most commonly caused by one or more DNS records in the Cloudflare dashboard pointing to a Cloudflare IP address. It can also be caused if your DNS record(s) reference another reverse proxy. To resolve this, you should edit your DNS records to point to your origin server’s IP address.

I see,
I’ve now found 2 DNS settings for killa-media .com
One was pointing to my hosting provider and one was a Cloudflare link.
It might have fixed it, but I’m not sure yet.
