# Github User Pages could not be update a pushed post immediately

A few days ago, I pushed a post to my github user pages (not project pages); this site,repository using jekyll, but the post nevertheless had been gave me a 404 error. the below steps are what I did until to fix a bit of problem.

1 Checked my post contents. 2 Checked my _config.yml.

the _config.yml was below:

baseurl:     /
exclude: [vendor]
excerpt_separator: "" # workarround for "highlight tag was never closed error"
gems:
- jekyll-sitemap


then, changed it as following:

baseurl:     /
exclude: [vendor]
gems:
- jekyll-sitemap
highlighter: rouge
markdown: kramdown
kramdown:
input: GFM


3 Contacted to Github to ask about this problem. 4 Do bundle update on your local jekyll due to update your gem github-pages if you using. That’s why github-pages gem have updated from v2.4.0 to v3.0.3. 5 Waiting to reflect changed.

I realized new post to pushed then it will take about 1 or 2 days over. I did not know why the update take long times to reflect the changes so like that.
