Installing The EC Internet Magmi Full Indexer Plugin

Some versions of Magento will not require this step. See Appendix 1, Magento Versions for more information.

Importing products with Magmi will often require reindexing of your product data in Magento in order for them to appear on the site. EC Internet offers an extension to automate this produces. Upon completion of a RAPID Web Sync, Magmi will initiate a full reindex of your Magento site data automatically.

This plugin is packaged with the RAPID Web Sync extension for Magento. Extract the Magmi Full Indexer archive you received with your purchase of the RAPID Web Sync extension, and copy the “plugins” folder directly into your magmi folder on the server.

Your installation of the EC Internet Magmi Full Indexer plugin is now complete.
