Replace Legacy Widget and Install Memcached

Today we replaced a legacy search widget with its block based counterpart on Hertfordshire alumni society website. Legacy widgets cause a documented bug in WordPress core that breaks the admin widget control panel in lots of cases.

We also installed and configured Memcached persistent object cache as the oversubscribed options, posts and rows tables in the database were all causing WordPress to recommend this action.

We then diarised to check in on the site in 1, 3 and 7 days to make sure Memcached was configured to have enough memory available for the site.
