I searched here and saw #422, went ahead and made the changes but that didn't fix it for me. So, I went ahead and deleted/cloned this repository again and ran `python setup.py install` again, started `jupyter notebook` and navigated to my `/nbextensions/` and I see codefolding is sitll enabled. I disabled/enabled it again and loaded up a notebook but I get the following: \r\n\r\n```\r\nmain.min.js:24082 Default extension for cell metadata editing loaded.\r\nmain.min.js:24168 Raw Cell Format toolbar preset loaded.\r\nmain.min.js:24216 Slideshow extension for metadata editing loaded.\r\nmain.min.js:28971 actions jupyter-notebook:find-and-replace does not exist, still binding it in case it will be defined later...\r\nmain.min.js:12109 Loading extension: usability/toc/main\r\nhttp://localhost:8888/nbextensions/codefolding.js?v=20160222101811 Failed to load resource: the server responded with a status of 404 (Not Found)\r\nmain.min.js:12132 Failed to load extension: Array[1] Error: Script error for \"nbextensions/codefolding\"(…)(anonymous function) @ main.min.js:12132\r\nmain.min.js:12109 Loading extension: usability/chrome-clipboard/main\r\nmain.min.js:23370 Session: kernel_created (d5ffa412-12fa-41c6-8eff-61e5d8c10255)\r\nmain.min.js:22673 Starting WebSockets: ws://localhost:8888/api/kernels/6ccdc32a-47a7-4225-b4ad-a108b10124ba\r\nmain.min.js:12109 Loading extension: usability/codefolding/main\r\nmain.min.js:22329 Kernel: kernel_connected (6ccdc32a-47a7-4225-b4ad-a108b10124ba)\r\nmain.min.js:22329 Kernel: kernel_ready (6ccdc32a-47a7-4225-b4ad-a108b10124ba)\r\nmain.min.js:12109 Loading extension: widgets/notebook/js/extension\r\nextension.js?v=20160222101811:81 loaded widgets\r\nmy_notebook.ipynb:1 Font from origin 'null' has been blocked from loading by Cross-Origin Resource Sharing policy: Invalid response.
