I've checked the item menu... It's just public, and when I put an other item menu on the return page, it's exactly the same result... Yes sure, I'm in 3.0.1... I would like to have made something wrong, but, when I'am in V2 it's works well, and I've just updated to V3.0.1 withou touch anything...And that doesn't work... it's a crazy thing.
If you prefer, when I put nothin on the return page field... I've got the same thing : "please log in before", so, it's not a problem of right. I'm sad, I understand nothing, I understand what you say, but I don't know what to do more...
Some thing new : when I'm not logged in, the sytem redirect me to
www.mysite.org/marche-rouge
/product/listing, after cancellation, but, if I'm log in before checkout, it's going to the good page, after cancellation.
Everything works well if you started from a new installation ? Without ask login ?
