Ok, it has taken me three weeks to get this bloody thing sorted, but here we go.
We have lost all postings since the database corrupted (sorry Julie and RAB), but there were only a small number of them.
Anyway, we are now running on new physical hardware, and the error forced me to do a badly needed complete rebuild of the virtual machine as well. We are up to the latest releases of both FreeBSD and WordPress.
The VM is running with four times the memory, five times the free disk capacity and double the number of processors.
I am sure I will hear about any problems.
Bear with me while I get the theme (look and feel) sorted.
