Yep, the first set of credentials are working for me this morning, too – not sure what went wrong previously.
Unfortunately I didn’t find anything in the settings to help me replicate locally. I’m really sorry about that but, realistically, I don’t think there’s going to be much more we can offer here – particularly as this seems not only to be specific to your theme but to your theme as it’s configured, in your hosting environment.
So, sadly, on this occasion I think we’re going to have to bow out.
