OK, this is driving me kind of insane now, so any input would be appreciated.
The background: Site has been up and running for a few months now with pages, custom theme based on Automattic's Underscores, WP-Ecommerce and a few other well-proven plugins. Nothing crazy, nothing outrageous.
The problem: Permalinks on posts have recently started 404-ing. Pages are fine, but aside from the primary blog listing page the blog permalinks are not playing ball on any setting aside from the default.
I'm fairly well versed with WordPress, and have done all the usual tests - specifically:
- The standard plugin witch-hunt
- Template switch
- rewrite_rules table flush
- .htaccess regeneration
- Default permalink structure (which works as it should)
The site is running a tad slow, but that's down to the shared hosting - I've checked that avenue also and am happy that isn't the problem. I could update to 3.5, but I've just had to roll back to 3.4.2 for a couple of clients as there seem to be some buggy aspects still so don't wish to do that. Particularly as the problem has only just manifest after working fine.

Anyone got any thoughts?
