Magento Configuration

The following chapter describes some of the basic Magento settings and features.

Please note that Magento configuration, installation, maintenance, customization etc. is beyond the scope of our support. But since Magento is very popular platform you can find tons of useful tutorials and articles on the web. Here are some resources for start: Useful links

Cache Management

Magento’s cache management system is an easy way to improve the performance of your site. Whenever a cache needs to be refreshed, a notice appears at the top of the workspace to guide you through the process. Follow the link to Cache Management, and refresh the invalid caches.

To access the cache management screen, you can also use the link in the admin panel menu: System > Cache Management.

Always refresh the cache after making changes in the configuration of your Magento/themes/extensions or after making any custom changes in the files.

Flush cache

Go to System > Cache Management. Click the following buttons to completely clear the store cache:

  • Flush Magento Cache
  • Flush Cache Storage

Disable cache

Go to System > Cache Management. Click Select All link, select Disable in Actions field and click Submit button.

Enable cache

Go to System > Cache Management. Click Select All link, select Enable in Actions field and click Submit button.

Refresh cache

If the cache is enabled, after each configuration change, extension installation, upgrade or uninstallation always refresh the cache. Go to System > Cache Management. Click Select All link, select Refresh in Actions field and click Submit button.

Index Management

Magento reindexes automatically whenever one or more items change. Actions that trigger reindexing include price changes, creating catalog or shopping cart price rules, adding new categories, and so on. To optimize performance, Magento accumulates data into special tables using indexers. As the data changes, the indexed tables must be updated—or reindexed. Reindexing is performed as a background process, and your store remains accessible during the processes.

To access the index management screen, go to System > Index Management.

You can reindex in any of the following ways:

  • using a cron job (preferred)
  • using console command which reindexes selected indexers, or all indexers, one time only.
