Solved Error Kunena discuss

Hi I use joomla 4 with php 8 and litespeed as cache
Kunena discuss 6.01 doesn't work well, when I post an error message, it opens the post in the designated forum, but the message written in the article page is not there.
I have debugging enabled and it says I have a lot of errors:

what can I do?

 

Clear the cache, then disable the litespeed cache and test K-discuss. If the error persists, please create a configuration report .

Thanks for the advice. I did some tests
I took out litespeed and I'm using jch, but the result doesn't change.
With the super user profile it works, while with the registered profile it doesn't work.
I removed the quick answer and used the link that points to the forum. This way it works.
I keep it like this.
