Because WordPress is a complex software application, there's an ongoing need to keep it up-to-date in order to take advantage of security fixes, new features, and revisions made necessary by changes to outside software services, hosting environments, and web browsers.
WordPress core usually updates itself automatically for minor version changes, but plugins and themes typically do not. Even core updates are better handled manually, following a full backup to permit rollback, as occasionally a change in core can break a plugin or even render the website inoperable.
We offer a fixed-price WordPress software maintenance service to apply core, plugin, and theme updates for your website safely and automatically as often as is necessary. We can also do these on demand at an hourly rate. Contact us for details.
