Troubleshooting

Open the console (F12) in the browser and enter dataLayer. The events must be in the list.

• If they are, the problem is in the tag setup in Google Tag Manager. Use Preview.
• If they are not, check that the module is on, the license is valid and the events are turned on.

Turn off Insert the container into the page if the theme or another module inserts it. If the Cookie banner module inserts it, it is not inserted a second time.

The purchase is sent only on the order confirmation page. Payment gateways that do not return the customer to the shop will not show it.

Change the Product identifier in the settings (ID, ID with combination, reference or EAN) so that it matches the feed.

In third-party checkouts (one-step) measurement is not supported yet. In the standard PrestaShop checkout it works.

They are off by default and are sent only with Marketing consent. Check that they are on and that the visitor has consented.

If an update fails, it usually rolls back by itself. If it did not, the original version is saved in this folder:

modules/.mvkit/backup/mv_gtm@<version>

Rename the modules/mv_gtm folder (e.g. to mv_gtm_new) and rename the backup folder to mv_gtm. The settings remained in the database.

If you cannot solve a problem, write to support via the contact page and include:

• the module version (shown in the License panel) and the PrestaShop version,
• the exact error text (ideally a screenshot),
• a description of what you did and what you expected,
• the address of your shop.

Support and updates are included for the first 12 months after purchase.
