Hi Douglas,
Thanks for the follow-up. Here's why this happens.
Why Joomla can't confirm these two plugins
During the Pre-Update Check, Joomla lists every enabled non-core system plugin as a "Potentially Serious Problem" by default. It only removes a plugin from that list if it can confirm compatibility through an update server linked to that plugin itself or to its parent package.
SP Page Builder installs as a component (com_sppagebuilder), and its plugins are installed alongside it. They aren't wrapped in a Joomla package, so:
- System - SP PageBuilder and System - SP Page Builder Pro Updater have no Package ID and no update site of their own.
- The update site belongs to the component, and its update manifest declares Joomla 6 support (
targetplatform includes 6.0–6.5).
So Joomla shows the component as compatible but can't link that to the two plugins, and it falls back to the generic warning. It doesn't mean the plugins are incompatible. It only means Joomla can't check them automatically.
Has it changed in the last 2 months?
The warning still appears in the current release (SP Page Builder 6.10.0), because the extension is still structured the same way. Functionally, SPPB 6.x is compatible with Joomla 6, and you can safely ignore this warning (see our docs: Joomla's Pre-Update Check).
Recommended steps before upgrading
- Take a full backup (files and database).
- Update SP Page Builder to the latest version (6.10.0), and update your template/Helix framework if you use one.
- In the Pre-Update Check, tick the confirmation checkbox for the non-core plugins warning and continue. You don't need to disable the SPPB plugins.
- After the upgrade, clear the Joomla and browser caches and check your pages.
If anything looks wrong after the upgrade, share the details here (or under Add hidden content if they're private) and we'll take a look.
Best regards,
