For some unknown reason, earlier on today I found this (WordPress) site replaced by a search field and a submit button. Nothing else…..
After scratching my head and reinstalling WordPress I managed to get everything back with a backup, minus my latest post (which I’ve luckily just found cached on Google).
I’m still not sure if the problem was a security, theme, plug-in or PHP issue.
Lesson learned – automatic backups are a must.
