After adding a new remote site setting into managed release package, even simples one like https://www.test.com, upload the package, try to install the upgrade package into other org, the screen gets stuck while clicking "Continue" button, doesn't go next step as usual.

There is a javascript error in console:
ReferenceError Can't find variable: onLoadSelector

However, there are two remote site settings we added couple months before, they are not affecting package installation.

Thanks!
