I wrote the same text I sent in the attachment in the main body of a post here.
Then I clicked ‘Submit’ but the post didn’t appear as a new post.
I didn’t see any warning when submitting, just the screen did not move from the editor page.
I did it at least five-six times at 2 am and then early in the morning.
As the post had many url links I though the codes in the links were the culprit somehow.
So I put the post text in the attachment and it was posted.
Thank you for the additional details. As luck would have it, I happened to see a settings in the forum configuration yesterday related to your issue. It seems things are set to limit URLs in a post to 6. I certainly would have hoped it would have told you why it did not post though!
I will try to test the limit to see if I get a notice somewhere on the page, but as an admin, it may bypass the rule for me. If you would, please try to post the reply you wanted to post, or any new reply with > 6 URLs in it, and look around the page to see if it says anything about the limit, anywhere?
I sent the text again.
Now after 'Submit' the screen comes back to this thread page but the post seems that went lost.
I could not see any warning.
I did a 'Quick reply'
