As an example we have an inline dcsMultiTrack call on an external link:
We are using v10.4.12 for the Webtrends tag.
Do you see utag.80.js firing in the network logs? I want to make sure the tag library is actually loading so we can pinpoint the issue.
Also, what tool are you using to filter/find the call? If you're using a network logger then what are you filtering on in the logs to find the call?
The reason for the failure is _tag is undefined. It doesn't execute the return statement because the conditional fails.
Looking at your Tag Configurations, you have selected Code Version 10.4.12. However, the template is loading version 8.4.2. Please ensure the correct Code Version is selected from the drop-down, then delete the template. You can do so by expanding the Advanced Settings (while in Edit mode), clicking the Edit Templates button, then when the Template Config modal appears click the Trash Bin icon in the upper-right corner. Apply all changes then Publish the updates. This should do the trick. Let me know how that works for you.
My presumption is that when the tag was first added the Code Version was changed to 8.x.x from the default of 10.x.x and published. Then later the Code Version was changed back to the default but the template wasn't deleted so that correct 10.x.x template version could be loaded in - so the old 8.x.x template was still being incorrectly referenced.
Anytime the Code Version or Tag Type drop-down is changed in any tag it requires the current template to be deleted so that correct template can be pulled in.
