So I’ve waited for about 3 hours, and finally the changed were made. I worked with some other files in the meantime, but I don’t know if that was the solution. The problem that the HTML file does update quickly, while the CSS file doesn’t update before 3 hours still persists, and I’m still interested in hearing how I can improve the CSS update speed for GitHub pages. 

Hi,

When I first started using GitHub pages, I also had the same experience. It is not GitHub’s fault, instead it is your browser. The solution to this is by going to your browser settings and reset cache and cookies. This should work.

Another way of doing this is by using Git. You make your changes on your local desktop, and see what the website looks like by opening index.html . Then you can git push it to github and be rest assured that it will be like what you saw in your local desktop.

I have tried deleting the cookies and resetting the cache in Chrome, but it doesn’t help. Also, I’m using both GitHub for Desktop and also directly modifying the file on the GitHub website itself, but none of these work, unfortunately. 

About 4 hours and no updates happening. The files updated immediately in the repo, but not on the hosted page.

Finally the page updated…

I am experiencing the same problem.

When I use git to upload, the changes are only noticeable in incognito mode. But when I upload directly to github, the changes are noticeable after about 5 minutes.

same problem too yesterdy it takes 12 hour to updat the steelshet 

Just clear the browsing data in the browser settings and it will work.

Same problem for me too.

GitHub pages are not reflecting changes on the github repository. 

Hi everyone!

If clearing your cache/removing cookies doesn’t work as explained by @yangciou, I would recommend reaching out to private support with the name and link of the repository you are working with. They should be able to take a closer look.

Cheers!

It happened to me too. What i understand is you need to clear the cache of your browser. I try on other browser it is working fine. Please clear cache and try hope it works…

Was having the same issue and Ctrl + f5 did the trick for me (refreshes your cache)

No, that is not the solution.

The problem is that the content on gitHub from which the site is built, is not reflected in what github.io serves.

There is an unpredicatble delay which can be seconds or hours.

As the CSS files could also be cached locally, it would be nice if support for https://github.com/tkareine/jekyll-minibundle is added to GitHub pages. minibundle adds a hash of the contents to the filename, so that a different filename is used when changes are made, avoiding the cache altogether for updated files.

If you have / before you css file remove it.

Example 

<link rel=“stylesheet” href="/main.css" />

won’t work but

<link rel=“stylesheet” href=“main.css” />

will work

I have the same problem. This is some kind of url caching on the server, if you change the url by adding ?random=1 the file is there, but the old urls give old cached result. I’ve just uploaded the file to verifiy in google webmaster tool and I can’t validate because without ?anything I have 404.

There should be some kind of flush function in repo settings, where user is able to force update the content. Or maybe using the API.
