[fabio_offroadstore]

Hi, I have a strange problem. When I am logged and try to add an item to the cart I receive an error message (We can't add this item to your shopping cart right now. logged).
if i try when unlogged it work perfectly.

Hi @fabio_offroadstore

This issue may be from third-party modules.

First, check it with the error log. Go to var/ log folder and check exception.log and other logs for any error. And paste it here.

Try to disable all third party modules and check if the error still exists, then turn them on 1-by-1. I guess that will be the best solution.
