Hey, welcome to the group! From your description, it sounds like you're dealing with a JavaScript or asset pipeline issue, possibly related to how Bootstrap or jQuery UI is being loaded or initialized. Given the versions you're using (Rails 5.1.7 and Ruby 2.7.0), compatibility can be tricky, especially if the project you're cloning uses different versions or asset handling (like webpacker vs. sprockets). Since you're unable to upload images, I’d recommend double-checking your application.js and application.scss to make sure you're requiring the assets correctly, and also look at the browser console for specific JS errors. If you can post snippets of those files here, we might be able to help more directly.
