Hi there,

Thanks for reaching out.

The error typically indicates a compatibility issue between extensions and Joomla version, especially when using SP Page Builder together with EasyStore on Joomla. In newer Joomla versions (especially Joomla 6), some legacy class references or loading methods may fail if:

An extension is outdated

Or using an incorrect namespace/import

The class Joomla\CMS\Filesystem\Path does exist, but the error means it’s not being loaded properly in that context.

Solutions:

1. Update Everything (Most Important)

Make sure all are on latest versions:

• SP Page Builder
• EasyStore
• Helix Ultimate (if used)

Clear your Joomla and browser caches deeply.

Let me know if it helps!

Best regards,

Hi, i already have all updated from the start. as i told you, i'm testing the extension, on clean Joomla 6, helix ultimate, sp page builder pro, all latest version.

Thank you
