Hey there, thank you for creating such an informative system and blog.I have some problems implementing the Server-Side on Wordpress, and don’t really understand why.
After I’ve installed the gtm4wp plugin and connected it to your server-side plugin and made all the explained steps, I can’t open the preview mode in the web container and also receive am error in server-side like no client claimed the request (400).
But before implementing the server-side plugin the gtm4wp worked well and pushed all the data from dataLayers, also the preview mode was working.
Thank you so much for explaining to me that, in near future, I’m planning to use your gtm-server system and migrate here. You’re really simplifying that process a lot!
One more question, when I use my debug mode for both Web and Server container at the same time, both of them are firing the right events and when I stop the Web debug view, the Server-side stops receiving these events. Is that a problem or in the backend they’re still firing?
