Why do I see '_satellite is not defined' in my console?

There’s likely an issue with the DTM code installation. The code placement can be quickly checked by viewing the page source of the site and hitting ‘Ctrl / Command + F’ and searching for ‘satellite’ to locate the DTM code snippets. The header code should be placed in the head section of the html as close to the tag as possible. The footer code should be placed in the body section as close to the tag as possible.

If the code appears to be implemented correctly, click on the library file shown in the header code in the page source. If it shows 'File not found', the property needs to be published or the staging file needs to be used until ready to publish. The production library file is only available once the property has been published at least once.
