Error when submitting a file by a guest

[Boyblan]

Hello

since installing Jdownloads 4, I've noticed that when (guests) submitting the form for publishing files on the frontend, I get an error message.

Cordialy.

(Added by admin from the PM):

The problem is the page I get after submitting a file (I discussed it with Colin"There seems to be a conflict with Joomla 4.3 and jD 4.0.26.  Many users are having the same sort of problem - think it is to do with categories.  Believe the fault is in J4.3.0
").

The site sends me to an ERROR page. like this

0 - Invalid address: (to):
