The Matomo Javascript code shows a red cross (on IE) or a broken image icon instead of the 1*1 transparent Pixel

When Matomo is showing a red cross image, or a broken image icon, it means that tracking visits is failing on your Matomo installation. It is not expected and should be investigated to fix the root of the problem as soon as possible (in the meantime, your visits are most likely not recorded).

To see where the error comes from, open your website in Firefox, right click on the broken image icon, and click on View Image. This should redirect you to the URL yourwebsite.com/piwik/piwik.php?... and the error message should be showing.

  • If the error message mentions MySQL, the error might come from a broken MySQL instance or tables. Try to repair your MySQL tables (using phpMyAdmin for example).

  • If the error mentions failed to open stream: No such file or directory, this might be caused by missing Matomo files. Make sure all Matomo files are properly uploaded.

For other errors, explore the Matomo knowledge base or try the Matomo forums for more help.
