Troubleshooting

I see nothing in Meta

Check the Setup status panel: are the Pixel ID, token and consent filled in? The Pixel starts only after consent to the Marketing category. In an incognito window click Accept all and try again.

“Invalid OAuth access token” error

Generate a new token in Events Manager and paste it into the settings.

Events repeat or fail

Look at the latest errors in the queue. The queue is caught up by cron, so check that cron is running.

Meta ended support for the API version

Change the API version in the settings (e.g. to a higher one).

Events go only to Test events

Delete the test code in the settings. While it is filled in, server events do not go to ads.

The feed is not created completely

Use the cron/feed.php command. If your hosting does not allow it and the address does not call itself after the limit (the hosting blocks a call to its own domain), set up cron for the &part=feed address every 5 to 10 minutes.

Meta reports a duplicate ID

With the Reference marking, the reference of every combination must be unique.

Meta did not find the image or price

A product without an image does not get into the feed. The price must be greater than 0.

Neither the admin nor the shop works after an update

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_pixel@<version>

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

Contacting support

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.
