Sitecore 7.1 "Select media" button disabled

Question

I have the following issue after upgrading Sitecore for one of our projects from version 6.5 to version 7.1: after the upgrade the "Select media" and "Insert link" buttons in the dialog boxes with the same names (in content editor) are not working. The "Select media" button is permanently disabled and the "Insert link" button does not respond, even though it is active. Also, in both dialog boxes, the Cancel button is enabled but non-functional (it doesn't close the dialog box when clicked). Could you please provide any hints or tips for debugging this issue? Did anyone else experience this behavior on Sitecore 7.1 ?

As I mentioned in the comments, check the JavaScript console of your browser to make sure there is no errors. Press F12 to open the dev console and try running the action again.

Make sure you do not have any of the default Sitecore files from a previous version checked into your project, otherwise they will simply overwrite the newer files when you deploy and functionality may break (I had a similar issue recently and it took a while to figure out).

I find WinMerge really useful, you can compare entire folders and it will tell you if there are file differences and/or missing files. Use the default Sitecore zip version of the root to compare your deployment again.
