Sometimes you may receive an error message when indexing your product data feed. These errors do not affect the normal functioning of the search function on your site, they only affect the updating of the products. However, we have put together this guide with the most common errors and their solutions to help you fix them as soon as possible and ensure the correct functioning of the indexing process.

Indexing Error Messages:

⚠️ Couldn’t find the feed – [product][URL]

What does this mean?

Probably, the URL provided does not exist.

This error may also mean that your server lacks sufficient resources, especially PHP memory, to deliver the data feed.

  • This error doesn’t affect the normal functioning of the search function in your site, only affects the products updating

What should you do?

  • First check that the URL provided is correct and then check your server resources to increase them, if necessary, to avoid this error.

⚠️ Your server is responding too slow (download speed under 10Kb/s). Process has been aborted. – [product][URL]

What does this mean?

The speed of your download could depend on how busy your server is at the time of indexing the feed. In addition, if the speed is below 10 Kb/s, the indexing task is aborted.

  • This error doesn’t affect the normal functioning of the search function in your site, only affects the products updating.

What should you do?

  • We recommend that you contact your hosting provider to make sure that the delivery speed is higher than 10 Kb/s.

    • Europe: 54.171.4.216
    • USA: 52.2.218.41
  • Please, check that the feed is not cached.
  • If the error persists, you need to contact your service provider to find out the reason why your server delivers this error.

  • If you get this error in PrestaShop, it is because the security hash that has been activated in the module is missing. Find this security Token in your plugin configuration, copy it and paste in your Doofinder admin panel > setup > indices > indices. Then re-index the feed.

⚠️ Your server is requiring authorization credentials to access the file. Please provide them – [product][URL]

What does this mean?

The site URL is probably configured with htaccess.

  • This error doesn’t affect the normal functioning of the search function in your site, only affects the products updating.

What should you do?

You can include the access credentials in the URL of the feed so that it can be indexed, for example: 

  • http: // usr: psw @ server / Tests

You can also include our IPs so that those credentials are not required. They are: 

  • Europe:  54.171.4.216
  • USA: 52.2.218.41

⚠️ The feed “URL” is empty // All feeds are Empty – [product]

What does this mean?

The feed can’t be generated correctly as you may be trying to index too many attributes or variants.

  • This error doesn’t affect the normal functioning of the search function in your site, only affects the products updating.

What should you do?

  • You can paginate the feed from your Doofinder admin panel > setup > indices > indices, or reduce the feed attributes to the essentials.

⚠️ There is a problem with your feed’s XML syntax

What does this mean?

The feed you are trying to index does not have a valid XML format, which causes a “Syntax error”. This occurs when the feed has not been completely generated, element names or attributes are incorrectly formatted.

  • This error doesn’t affect the normal functioning of the search function in your site, only affects the products updating.

What should you do?

  • Make sure the feed is fully generated. An XML element whose name starts with a number is illegal XML.
  • Some of your attributes might be using a wrong format. XML elements must follow these naming rules:
    • Names can contain letters, numbers, and other characters
    • Names cannot start with a number or punctuation character
    • Names cannot start with the letters XML (or XML, or Xml, etc)
    • Names cannot contain spaces

  • This error doesn’t affect the normal functioning of the search function in your site, only affects the products updating.

What should you do?

  • If your website requires logging in order to view the content, avoid redirecting to the login page when Doofinder tries to access the feed URL.
  • If the site is blocked by HT access, you can include the access credentials in the URL of the feed so that it can be indexed, for example: https://user:password@mydomain.com

    • Europe: 54.171.4.216
    • USA: 52.2.218.41
