Middleman Not Found Error (File shows in Sitemap)

I removed the old post and I decided to better clarify the problems.

  1. I moved the images from /img/ directory to /images/, then I removed the /img/ directory and updated all html.erb and partials files to point to /images/ instead of /img/.

  2. I installed bootstrap (manually, I had some problems with bower so I decided to do “the easy way”).

Then I decided to run “bundle exec middleman build --verbose --clean”. As you can see, the command execute normally, but there is a “not found” error in .svg bootstrap font. The font shows in sitemap.

The images don’t shows error but when I access in the sitemap, shows a “not found” error.

PS C:\Bitnami\wampstack-5.5.25-0\apache2\htdocs\geteloquent.github.io> bundle exec middleman build --verbose --clean

BUNDLED WITH
   1.10.6

I cried when “I” found the error.

My client (who is a programmer too haha) said it was simple because the images and also the glyphicons from Bootstrap had numbers after the file name. Example: file-12345.jpg.

I changed the file name and everything worked fine :smiley:
