Returning the symlinks alone to previous state didn't work. It looks like when it tries to install the new certificate - it puts in the symlinks to itself - it then displays the cat errors as no certificate can be found. It looks like this error is recorded in dbipsconfig so it doesn't read the symlinks when corrected. Hence a restore was required to fix it (I couldn't investigate via phpMyAdmin as that required a working certificate to access). And yes I did service apache restart. Hi - are you in Croydon? I'm in Sydenham.
