Solution for Magento 2 Community Edition (CE / Open Source)
If you get the error "Product Key is empty or invalid. The extension has been automatically disabled." while saving Magefan extension on Magento Community edition and don't see any Product Key field, as on the screenshot:
Attention! Magefan Community is not a Magefan Blog or e.g. Magefan Login as Customer, it is a separate module that is used together with Magefan extensions.
To check the version of the Magefan Community extension have a look inside one of these files:
If you have an old version, then you need to update the extension.
If you have the latest Magefan_Community version, use Magento Community (not Magento Enterprise) and the issue is still there, please contact us.
Solution for Magento 2 Enterprise Edition (EE / Commerce)
Magefan extensions are paid for Magento EE, but until some versions, we didn't require a product key. Developers were able to download them from GitHub or other open places and use without actually paying. In the latest versions, there is added the product key field. If you use a free version (do not have any paid orders) you need to purchase Magefan extension for EE to be able to use the recent version.
What is the difference between Magefan extension for Magento Community and Magento Enterprise, why it is not free fro Enterprise?
- Magefan extensions code was made to be completely the same as for Magento Community (CE) and Magento Enterprise (EE). We made one extension (code) for both Magento editions to maintain it easier. Magento EE has additional functionality (modules), one of the examples is a page builder or catalog restrictions, and in our code, we made sure the extension does not conflict with them and works properly. A module included EE only specific code, that's why it the same code, but it is free for Magento CE and paid for Magento EE.
