Concrete CMS Support and Maintenance

Concrete CMS — formerly known as Concrete5 — is a PHP-based content management system known for its in-context editing experience, which lets content editors update pages directly in the browser without switching to a separate backend. It is a practical choice for organisations that want their content team to feel at home managing the site without relying on developers for every change.

Xpose provides Concrete CMS support and maintenance for businesses across the UK. We handle the technical side of running your Concrete CMS installation — keeping PHP and the framework up to date, maintaining add-ons, applying security patches and fixing the issues that inevitably arise over the lifetime of any live website — so your editors can get on with publishing content.

What Concrete CMS maintenance involves

Concrete CMS releases regular updates to the core framework, and keeping up with them is important for both security and compatibility with newer PHP versions. Each update needs testing against your installed add-ons and any custom blocks or themes your site uses, because changes to the core API can break extensions that were written for an older version. We manage this process carefully, using a staging environment to verify everything before touching the live site.

PHP compatibility is a recurring theme in Concrete CMS maintenance. Server environments move forward — hosting providers end-of-life older PHP versions — and if your Concrete CMS installation and its add-ons are not kept compatible, you can find yourself stuck on a vulnerable PHP version or facing a sudden outage when the host upgrades without warning. We keep your stack compatible and ahead of these changes.

Common Concrete CMS problems we fix

The Concrete CMS issues we handle most regularly include broken add-ons after a core or PHP update, the in-context editing toolbar failing to load correctly, file manager errors when the storage location or file permissions change, and custom block types that stop rendering after a theme or core upgrade. These are all solvable with the right access and familiarity with how Concrete CMS is structured.

We also frequently assist with performance and caching issues. Concrete CMS has a flexible caching system, but it needs proper configuration to avoid serving stale content on one hand or hammering the database on the other. Slow page load times, high server load during page saves, and search index problems are all performance concerns we have resolved for Concrete CMS clients.

Ongoing Concrete CMS support from Xpose

Our Concrete CMS support service covers core framework and add-on updates, PHP and server environment compatibility, security patch monitoring, caching and performance configuration, and hands-on fixes when the site or editor experience breaks. We support both older Concrete5 installations and current Concrete CMS versions.

Xpose is a Norwich-based web design and development agency with experience across a wide range of PHP CMS platforms. If your Concrete CMS site was built by someone who is no longer available, or if your current technical support arrangement has gaps, we are happy to review what you have and take over the ongoing maintenance.
