Next entry link not shown in FireFox

Hi,

I’m encountering an odd bug and was hoping someone could help track down the source.

We’ve launched a diary-style microsite and are posting new entries each day.

But the prev / next links (below the post) stopped work properly after entry 46 and now only displays the previous link on FireFox and IE (Chrome is OK).

I didn’t notice at first as it works normally if I’m logged in, but every entry after #46 doesn’t have a next entry link.

Checking the code, the next code isn’t present on posts after #46 – they all show only the previous link. Otherwise new content is posted and displayed properly (and I don’t think there’s been any change to how the content is being published – it was mostly written upfront and scheduled in batches).

Any help would be appreciated on this one.

Thanks,
Scott
