I'm trying to debug a Sencha 2 Application. A previous developer wrote it and left.
When I go to one particular page in this Sencha application, the app shows the spinner icon and never loads the page. The problematic page does involve loading content from an external URL. However, if I manually enter that external URL into a web browser, it loads correctly without issue and has the correct content.
I also tried setting up a webserver to point at the Sencha app and I tried navigating to the problematic page in the desktop version of Google Chrome. However, the problematic page loaded fine when I got there. There was no error in the Chrome developer console either.
Does anyone have any good debugging advice about what I should try next? Or some hints about what might be causing the problem? Is there some sencha debug console that I can enable/view in the published app?
Thanks
