This website uses several applications that use the programming language PHP.
PHP has been successfully upgraded to PHP 7. While every attempt was made to minimise disruption, it is likely that there were periods when the Harvard Referencing application was not available.
Apologies for any disruption during upgrading that finished yesterday at 18.00 hours as planned. Hopefully users will see a significant increase in speed of use.
Most applications that worked using PHP 5 required some rewriting to work using PHP 7.
