Hey Heidi,
Thanks for reaching out to us. Before getting too far afield with this issue, I know it seems like a small detail right now, but can you clarify exactly what you mean when you say this:
but it makes a fallback on the ajax.js.
1. What do you mean? And is ajax.js something within your theme?
Also, thank you for noting that your work is local right now. That might make troubleshooting quite challenging, unfortunately.
The example you’re citing in that Themer’s Guide article is just for replacing the default Tribe stylesheets – so, to be clear:
2. Have you added the CSS files that you are calling from your replace_tribe_events_calendar_stylesheet() function into your theme?
Finally:
3. Can you paste your custom replace_tribe_events_calendar_stylesheet() code into a Gist at http://gist.github.com and then share a link to that Gist in your reply?
Thank you in advance for addressing each of the three items here Heidi – it’ll give us a solid foundation for further troubleshooting and such 🙂
Cheers!
George
