Can't find Suppliers

out2day

You can no longer search by supplier.
This wasn't a problem a while back.

I've just made a test, and it worked correctly for me.
It displayed to me all the products linked to the supplier I searched:

If you are having problems with this filter, perhaps there could be some kind of conflict with a 3rd party plugin.
You can try to disable all your plugins except WooCommerce and ATUM, and try that way.
If it works, you can start enabling them back one by one until you find the source of the conflict.

Best Regards,
