You have a 403 error on the template.collector.ac site, this usually indicates a permissions issue. You will want to contact your web host provider and ask them to investigate.
The 403 forbidden error is still there. Chances are, we don’t have read access to the directory. I’ll post in a separate private reply a screenshot for reference.
I was able to view the page, that error is from the developer tools console.
Glad to hear it’s all working now. I did revisit your page and the error is no longer there. It must have been some kind of weird hosting problem. Anyway, enjoy BB!
