Solved Succecfully installed but NO kunena at components

I'm glad to see that it's working again. 

Hello rich!
I am sorry for bothering you again. I had some problem with image uploading to my Joomla and in Joomla support they say the problem is I Kunena.

My question was: Hello
When I want to add article in my Joomla 4 and go to tab: Images and Links....then Want to SELECT image from media it takes me to this page in the attachment. (404 error page)
what is wrong?
Can you please help?

So their answer after my FPA diagnosis was:

1. There is a problem with Kunena 6.0.2 but that is all I can see at the moment.

2. Looks like Kunena is causing an error? Check you have set Permissions correctly in it.
Also the logs folder is in the root which suggests your Joomla has been migrated. Possibly something in the migration failed?

Here is the link to our conversation:  forum.joomla.org/viewtopic.php?f=811&t=9...0&p=3670371#p3670371

Can you please help? What went wrong?

just a question about this
Can you just upload an image in joomla in administrator/content/media ?
And which text editor do you use and is it up-to-date
And I notice that you have installed a kind of slider in the website which? type name
And also that you may have switched joomla template too give that name and version here
and also a kunena configuration rappoet just to be sure

Thank you
1. Yes, I can upload image just in kunena media.
2. I cannot upload image to article via IMAGES AND LINKS tab in article page (backend)
3. My problem was before I uploaded new template and new slider. My problem was after I had problems with Kunena. But at that time I thought that was not big problem because I could upload images manually.

did you set error reporting to maximum ? to see if there are more error messages.
And also tried to put the Default Editor on tinymce in administrator>Global Configuration and save it and then see if that works.
What I'm also thinking about is to check whether your htaccess is the last one and not the one from joomla3, which can often be seen by date or large
or test it with without the htaccess by renaming the old one

This second problem seems to be solved and hjad nothing to do with Kunena.  forum.joomla.org/viewtopic.php?f=808&t=9...9&p=3671115#p3671220
