title: Unable to change Git account
body: <p>I tried to push to my repository, but I got the error below:</p>
  <pre><code>git push origin master
  remote: Permission to PhanVanLinh/phanvanlinh.github.io.git denied to edgarphan.
  fatal: unable to access 'https://github.com/PhanVanLinh/phanvanlinh.github.io.git/': The requested URL returned error: 403
  </code></pre>
  <p>Before, I was using username <code>edgarphan</code>, but I have already changed it to <code>PhanVanLinh</code>, but it still keeps <code>edgarphan</code>.</p>
  <p>I have tried to delete the project and clone again, uninstall Git and reinstall, but it won't work.</p>
