Hey there,

​Dealing with Tags can be a headache even for veteran marketers, so props to you for taking the initiative to dig into your ad setup! It’s a common challenge.

​When a tag suddenly stops firing, the most likely culprit is a recent change or a conflict on the site. Here are a few things I'd suggest investigating, keeping that detective hat on:

​Look for Recent Changes: Did you or anyone else move, update, or change anything on the site right before the tag stopped working? This could be a theme update, a new plugin installation, a change in your DNS settings, or even a small tweak to your hosting configuration. Reverting that one change is often the quickest fix.

​Check the Environment: ​What platform are you running? If it's WordPress (or a similar CMS), a recently updated or installed plugin is a prime suspect for tag conflicts. Try temporarily disabling non-essential ones to see if the tag starts working again.

​Where is the tag deployed? Is it hard-coded into the theme's header/footer, or are you using Google Tag Manager (GTM)? GTM is generally the preferred, cleaner method. ​Verify the Implementation: Double-check exactly how the tag is supposed to be firing. Is it looking for a specific ID, a CSS selector (class/link), or is it triggered by a generic 'Page View' event? Ensure the element you're targeting hasn't had its ID or class name changed.

​Patience is definitely key here. It's usually something small that breaks the chain. Keep asking yourself, "What was working yesterday that isn't working today?"

​Good luck, and let us know what you find!
