FREQUENTLY ASKED

Questions merchants ask before buying

Does this work with my current Magento version?

Every MageRa extension is tested on Magento 2.4.6 through 2.4.9 community edition. If you are on an older Magento version, contact us before purchase and we will confirm compatibility.

Do I need Hyvä?

No. Each extension ships with both a Luma-compatible template and a Hyvä-compatible template. The Hyvä template is provided as a fallback module under MageRa_<Extension>/view/frontend/templates/hyva/.

What if I am on Adobe Commerce (Enterprise)?

The same extension works on Adobe Commerce. The composer package, module activation, and templates are identical. Some EE-only features (e.g. B2B out of the box) get extended by the same code without an EE surcharge.

Can I install via composer?

Yes — every MageRa extension is published as a standard composer package. Add the MageRa Packagist repository, run `composer require magera/<module>`, then `bin/magento setup:upgrade`. The full install snippet is on the extension detail page.

What is the refund policy?

30-day money-back guarantee, no questions. Email support@magera.ca within 30 days of purchase and we issue a full refund.

What happens if the extension doesn't work for me?

We offer a 30-day money-back guarantee. If the extension doesn't meet your needs, email support@magera.ca within 30 days and we'll issue a full refund — no questions asked.

Will this work with my other MageRa extensions?

Yes. All MageRa extensions share the same base library (MageRa_Base) and are tested together. If you find an integration issue between two MageRa extensions, support@magera.ca is the right address.

How do I get support?

Email support@magera.ca. Every MageRa license includes 3 months of standard email support with a 24-hour weekday response SLA. Critical production issues are flagged and triaged within 4 hours.
