Oops sorry Clause Lampert, i thought

<input class="btn btn-primary ossn-wall-comment" value="send type="submit">

was his original code .

For me the right syntax is

<input class="btn btn-primary ossn-wall-comment" value="send" type="submit">

Thank You "Nice guy", but the quotation-mark lacks only here in the posting, not in the original source-code. :-)

<div style="float:right;">
<div class="ossn-loading ossn-hidden"></div><input class="btn btn-primary ossn-wall-comment" value="Senden" type="submit">
</div>

It vanished when I edit it from the original "Senden" from my site to "send" here in the posting.

Hello,
At first a simple thing, you forgot to close the quotation mark after send .
I don't know if it can fix your problem but i think your syntax is not correct

Please send us your website URl, i shall take a look i am don't know why its behaving strange.

@Arsalan Shah
Sorry, but I don´t find the difference between what happens when I press [ENTER] (->Javascript) and pressing a submit-button in the form - element.
There must be something in the Javascript that sends something different than the submit-button, maybe an object ID or something like that.

I try to explain:
There is no comment and I press [Enter]: comment -1- appears. I press [ENTER] again: comment -2- appears. This is how it should be.

But:
There is no comment and I press "my" submit-Button: the message-box "error" appears and the comment isn´t stored. If there is a comment -1- and I press the submit-Button: comment -1- is duplicated and now there are two identical comments under the posting.

The reason you are getting the error box because the comment isn't posted see :

https://github.com/opensource-socialnetwork/opensource-socialnetwork/blob/v4.x/components/OssnComments/plugins/default/js/OssnComments.php#L53-L56

You have to look why the comment isn't really get posted and server sends 0 response (not posted/error in posting).

Behaviour:
First comment: when I click the button the message "Something went wrong! Reload this page and try again." appears.
Following comments: when I click the button, the previous comment appears again. When I want to save, for example, comment nr. 3 the comment nr. 2 will be duplicated. I think that the click on the button fails to send the correct object-ID.

Verhalten:
Wenn ich den ersten Kommentar absenden will, erscheint ein separates Fenster mit dem Fehlerhinweis "Irgendwas ist schiefgelaufen - versuche, die Seite noch einmal neu zu laden".
Wenn ich weitere Kommentare (z.B. Kommentar Nr. 3) absetzen will, wird der jeweils vorherige Kommentar (z.B. Kommentar Nr. 2) nochmals gespeichert. Ich habe den Eindruck, als würde der Klick auf den Button die falsche Objekt-ID übergeben.
Das Verhalten betrifft nur den Klick auf den Button, die ENTER-Taste sendet den Kommentar ordnungsgemäß!

Can't follow.
There's a posting on the newsthread. Ok.
Now someone is trying make a first comment: What error are you getting?
