Hi Brett,

I just got around to updating my previously working version (2.0, stored in Dropbox) to 2.0.5. After updating, the nav will load but cheatsheets won't. I decided to remove all layers (Dropbox, Fluid) and run it directly from local hard drive but get the same thing (Chrome or Safari - OS X Mav). When I check Dev Tools I see errors like this in the console:

Failed to load resource: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. file:///Users/khit/Dropbox/Apps/Cheaters/cheaters/cheatsheets/css3.html XMLHttpRequest cannot load file:///Users/khit/Dropbox/Apps/Cheaters/cheaters/cheatsheets/css3.html. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. cheat.html:1 Failed to load resource: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. file:///Users/khit/Dropbox/Apps/Cheaters/cheaters/cheatsheets/patternsregex.html

I noticed that jquery-1.7.1.min.js was removed in this version but I don't think that's the answer because my old cheat.html file was calling jquery-2.0.3.min.js anyway.

Any thoughts on what I'm doing wrong? Thanks! I love this thing! kh

If you're using it in Chrome, you have to load it from a web server, not from a file. You can do this with a virtual host locally or by placing it on a remote server (or possibly even from the Dropbox public folder with an http url). Let me know if that's the issue.

Yup, that's it! (I saw same in Safari too. And wasn't able to serve it using a Dropbox share link.) Thanks for the help!

Upon further review...

Apparently when you create a new Fluid.app it locks down browsing to only the local path used when initially creating the app. Head to Preferences > Whitelist to see/update this setting.

Given the new cheaters file structure I updated the URL (under Preferences > General) but failed to update the Whitelist. (I just chose Allow browsing to any URL). All good now!
