I am doing some work for a client and their version of Firefox 4 is getting JQuery undefined errors, whereas my version of Firefox 4 is fine. This is when viewing the exact same page (hosted online)! Every other browser on both my machine and the clients is fine.
Does anyone have any thoughts as to why this could happen? Could it be a caching issue? Javascript is definitely enabled on the browser.
Edit: Here is the log from the console where the jquery file load is attempted:
GET https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js [HTTP/1.0 200 Connection established 234ms]
Does ‘connection established’ mean that the file is loaded? Or should I be expecting an ‘OK’ response?
Are you loading a local copy of jQuery (instead of say a CDN) and this local copy is not in the client’s computer?
