Afraid I am going to ask that age-old question but, perhaps, the most important one. What has changed? If they worked and then ‘stopped working’ – something must have changed. I would suggest this to be the critical path….

Appologies for never replying to your post, I think I missed your reply.

I am pretty confident the conflict was with the All in One Security plugin, in case this is helpful to anyone else.

Not one I have come across but on the whole the so-called ‘security’ plugins I have encountered often cause many problems…
