Blank Page with error log about jekyll-admin

[nanocodex]

Update: The solution I found was to update jekyll-admin to the latest version:
gem 'jekyll-admin', '~> 0.11.1'

Also relevant

I got the following error when I tried launching Jekyll Admin on rack version 3.0.10:

internal:C:/Ruby32-x64/lib/ruby/site_ruby/3.2.0/rubygems/core_ext/kernel_require.rb:37:in `require': cannot load such file -- rack/handler (LoadError)

After searching, I found this post saying that:

As of version 3.0 Rack::Handler was removed from rack and pulled out into its own gem (rackup).

To fix the error, add gem 'rackup' to the gemfile:

gem 'rack'
gem 'rackup'

Update

Upon further local testing, it seems that Jekyll Admin has trouble allowing me to change and edit files when using the rack ~> 3.0 and rackup gems.

Respective versions that caused this bug to happen are as follows:

• Jekyll Admin 0.11.1
• Rack 3.0.10
• Rackup 2.1.0

Rolling back rack to a version below 3.0 (I used version 1.6.13) and hence removing the rackup gem seems to solve the problem. However, Jekyll Admin still says that it "could not fetch the config" even if the _config.yml file was successfully updated. Just like the issue linked, it has the exact same issue when updating any other file in the site.

Also to note

Regardless of whether Jekyll Admin is using gem "rack", "< 3.0" or gem "rack", "~> 3.0" paired with gem "rackup", the homepage configuration no longer works, instead always defaulting to pages. No matter what you set it as in _config.yml:

jekyll_admin:
  homepage: "posts"

The above configuration does not work.
