Question Trouble when clicking on submit button

Hi,
Since I have installed the 2 latest updated version of kunena (6.10 and 6.11), my registered users can not post their own message.
The problem appears once the message is ready to be submited to the moderator :
When a registered users click to the submit button he got an 0 Error message (as you can see attached)
Could you help ?
Thank you in advance
Michel

Hereunder you will find my working configuration
In addition in attachments area,I joined the error message file I got when I set joomla on debug mode
Please note the second attached file called KUNENA_ErrorsUsers_Attachments, this is what I get in the profile tab of the personal space of a registered user account

There is really no one to help me to solve this serious problem which prevents registered users from using my forum ?

you write "Since I have installed the 2 latest updated version of kunena (6.10 and 6.11),"
But did it work before and which kunena version was that?
or have you recently upgraded kunena version 5 to kunena version 6 ?

Dear Leen,
Thank you for answering.
Last february I have mooved joomla from V3.11 to the joomla4.2.8 Version. Of course I have then mooved to kunena 6.0.9.1 in following carefully the procedure upgrade from kunena 5.1 or 5.2 to kunena 6.0 described in kunena.org documentation.
The upgrading has been performed without problem and since I had no problem (and my registered users also) when using the forum on my wesite untill I updated to kunena V6.1.
The latest kunena version working well on my site was V6.0.10
Awaiting your comments

Do you also have these warnings / notifications if you have a
Testing with the Cassiopeia - Default template ?

I will try with casiopea template tonite and come back to you after

Hello,

I don't think that the issue is related to the Joomla! template. I will try to reproduce this issue locally

if I want to respond to a topic on my own  geupgrade test site
and in Kunena Forum: Configuration at SEO Settings Search Engine Friendly URLs is set to yes then that will not work
"404 View not found [name, type, prefix]: topic, html, site "
If I set it to No there, the response will work.
Could that also be the case with this problem?

Kunena Forum: Configuration at SEO Settings Search Engine Friendly URLs : I set it on No
I still have my problem when I write a message and I click on submit button for approval

Hello xillibit,
Thank you of taking care of my concern.
Awaiting your comments
BR
Mike
