AJAX stuck on loading screen

[kai920]

What are the steps to troubleshoot AJAX not working inside SMF/Joomla? It's always stuck with the green "loading..." bar at the top.

Do I have too many .js calls at the top of my template?

I see in the error console some errors with script.js, but I am not sure where to go from here.

PS. could this URL be a cause for concern? (mixture of SEF and non-SEF)
