Magento 1 offers a number of caches to speed up the loading of your content. When products are updated or the code on the site is changed, then you may need to clear the cache before your changes show on the front end of the website.
- Log into your Magento admin panel
- Navigate to System > Cache Management
- Tick the checkboxes beside all the caches you want to clear
- Select Refresh from the Actions dropdown
- Click the Submit button
The selected caches will be automatically cleared.
