Question No Avatar upload in user profile since K 5.1

Hi,
When a user will change the default profile image (Avatar) to a new image, the user is clicking Edit profile.
Then go to Avatar-image. Then the user will upload a new image with the correct size and file format. The image is shown at the desktop but in the console there is an error message "POST check.mydomain.de/profil/index.php?option=com_kunena .... &task=upload&format=json 404 (Not found)" (Screenshot).

After click at Save. The message that the profile is saved will apear. But when you go back to the profil/avatar page. There is nothing changed (No Upload, No Avatar).

I've testet on Version K 5.0.13 and every thing is working fine. But with backup from K 5.1 until now K 5.5 there is an upload no more possible.

I am using sh404sef and if I disable sh404sef it works! What can I do?

Maybe it's a similar problem:
www.kunena.org/forum/k5-1-support-archiv...n%C2%B4t-runs#202771

My .htaccess is OK.

I've testet with two different Templates and on my Server. I can see this request:

Template purity_III Template helix_ii
I am thinking there ist a problem with incorrect URL. Kunena is using a relative URL instead of a relative to site or absolute one .

You're right, but it's not the relative url, it adds a double slash to the path to "media" if you set in Crypsis "Load bootstrap css" and "Load Icomoon icons".
Can you please test something? Go to "/components/com_kunena/template/crypsis/template.php" line 87 - 93 and remove the slashes at the beginning before "media". Then empty the cache and test, whether it works.

I've done.
1. Crypsis "Load bootstrap css" and "Load Icomoon icons".
2. remove the slashes at the beginning before "media".
But it is the same problem. No Avatar ist uploading and "POST /profil/edit/index.php?option=com_kunena&view=user&task=upload&format=json HTTP/1.1" is still logging 404 (Serverlogfile).

What do you think about to "use of RELATIVE URL instead of JRouted URLs, which is not OK"?

I'm not sure, but know, that relative urls within the forum not always correct linking, when the Joomla installation is in a extra folder (not on root).

I've noticed on your page, that on the addresses it lacks the word "forum" such as:
webaddress/index
webaddress/recent and so on..
Are this addresses created by sh404sef?
If you open a topic it shows correct webaddress/forum/topicname

If you want upload a avatar the address is correct?
Should be .../forum/profile/edit/xxx-username.html (xxx is user id).
