As you may know, Magento no longer supports Magento 1. We don't recommend continuing to use Magento 1 past its end of life date.
Because Magento has EOLed Magento 1 and no longer supports it, we have stopped development and support on our own Magento 1 extension. We strongly suggest that you upgrade to Magento 2 and the latest version of our extension. This guide shows how to upgrade to our Magento 2 extension. Upgrading allows you to utilize the newest improvements and bug fixes from both Algolia and Magento.
If you wish to continue using the Magento 1 extension, you can post your question in Discourse or Stack Overflow. You can also take a look at our troubleshooting guide for Magento2 --a lot of our advice is useful for Magento 1 as well.
