Thanks samboll for the tip but it didn’t work, neither did turning off plug-ins or any of the other ideas out there I found in the forum. It must have been some sort of server side problem because the whole site became unavailable at one time – I walked away from the computers thinking a hack had just done me. 10 min later I came back for another go and to contact the hosting service when everything was back on-line and the Categories were working again – all perfect…
The loss of categories and sudden recovery without intervention seems to have happened to a few people from reading the forum. It’s a little disturbing and I’m still clueless as to what is causing it – but guess it’s server-side and out of my control – I’ll just keep praying!
Thanks
Matt.
