remove ?___store=default from Magento URL

To remove the “?___store=default” from your Magento URL, you can follow these steps:

1. Log in to your Magento admin panel and navigate to System -> Configuration.
2. Click on “Web” under the “General” section on the left-hand side of the page.
3. Expand the “Session Validation Settings” section and set “Use SID on Frontend” to “No”.
4. Expand the “Search Engine Optimization” section and set “Use Web Server Rewrites” to “Yes”.
5. Click on “Save Config” to save your changes.
6. Clear your Magento cache by navigating to System -> Cache Management and clicking on the “Flush Magento Cache” button.

By setting “Use SID on Frontend” to “No” and “Use Web Server Rewrites” to “Yes”, Magento will generate clean URLs without the “?___store=default” parameter. This will also help to improve your Magento website’s search engine optimization (SEO) by making your URLs more user-friendly and easier to index by search engines.

Note that if you are using a custom theme or third-party extensions, there may be additional steps you need to take to fully remove the “?___store=default” parameter from your Magento URL. In that case, it may be best to consult the documentation or support resources for your theme or extensions for more information.
