Hi The WeltPixel team,
I'm Jacker from Mageplaza. We have a shared customer which using Mageplaza One Step Checkout and your module WeltPixel_GoogleTagManager.
We would like to make it compatible with your module.
After investigating, we figure out the solution that:
Update file: WeltPixel/GoogleTagManager/Helper/Data.php at line 282 and 393
Add content:
With line 282
case 'checkout_index_index' || 'onestepcheckout_index_index'
see
line 393
if ($requestPath == 'checkout/index/index' || $requestPath =='onestepcheckout/index/index') {
see
After changing this, it will be compatible with Mageplaza One Step Checkout.
