Problème pixel Facebook - Page view

Je recherche une personne qui puisse m'aider pour installer le pixel Facebook car j'ai toujours une erreur Page view :

Facebook ppixel helper :
We detected event code but the pixel has not activated for this event, so no information was sent to Facebook. This could be due to an error in the code, but could also occur if the pixel fires on a dynamic event such as a button click.
