SilverStripe CMS Support and Maintenance

SilverStripe is a robust open-source CMS built on PHP with an MVC architecture that appeals to organisations needing a flexible, developer-friendly platform. Popular across the UK and Australia, it powers everything from corporate websites to government portals, offering a clean content editor interface alongside a powerful templating and module system for developers.

Xpose provides SilverStripe support and maintenance for businesses across the UK. Whether your site is running an older SilverStripe 3 installation or a current SilverStripe 4 or 5 project, we look after the ongoing upkeep — framework updates, module compatibility, security patches and hands-on fixes — so you can focus on running your organisation rather than managing server dependencies.

What SilverStripe maintenance involves

SilverStripe follows a structured release cycle with regular minor releases and occasional major framework versions. Each update can affect contributed modules, custom extensions and the ORM layer, so maintenance is never as simple as bumping a version number. We review your module dependencies before applying updates, test in a staging environment and promote changes to production only when we are confident nothing is broken.

Security is a particular priority. SilverStripe publishes security advisories regularly, and unpatched installations are a common target for automated scans. We monitor the SilverStripe security mailing list, apply patches promptly and check that your server configuration — PHP version, web server headers and file permissions — meets current best practice.

Common SilverStripe problems we fix

The SilverStripe issues we handle most often include template rendering errors after a framework upgrade, broken ModelAdmin configurations when a data model changes, and module conflicts that surface during a Composer update. We also frequently see sites where a PHP upgrade on the server has broken SilverStripe without any change to the CMS itself — something that requires careful diagnosis of error logs rather than a simple rollback.

Content editor problems are another regular support category: upload folders that stop working, WYSIWYG editor configuration that breaks after a TinyMCE or Silverstripe CMS module update, and permission configurations that inadvertently lock editors out of certain page types. These are familiar territory for us and are resolved quickly once we have access to the environment.

Ongoing SilverStripe support from Xpose

Our SilverStripe support service covers framework and module updates via Composer, PHP and server compatibility checks, security patch monitoring, performance optimisation including ORM query review and cache configuration, and direct fixes when something breaks. We work on both SilverStripe 4 and SilverStripe 5 projects and can assist with migrations between major versions.

Xpose is a Norwich-based web design and development agency with broad experience across PHP CMS platforms. If your SilverStripe site was built by a developer or agency that is no longer available, we are happy to review the codebase and infrastructure, get up to speed on how your site is structured, and become your reliable ongoing support partner.
