Hi,
One of the websites gives “failed to load resource” errors on my desktop while it works fine on my iphone ? How do I reinstall javascript for my OS ?
Your operating system has nothing to do with javascript. Javascript is a part of the web browser you use (IE, Firefox, Chrome, Safari). Each of them have their own javascript engine. A “Failed to load resource” error could be related to a script that’s trying to load an external file and failing - probably another script, like a javascript library.
If you don’t have access to the site’s server, you can’t change the code and fix the error.
