Why my replies to a topic become not visible?

I create a reply to a topic or a new topic and after that I don't see it in the forum.
It does not become visible.
Created an idea yesterday, replied to several threads and made a comment on one idea.
One reply became visible this morning and the comment on the idea already yesterday.
If you write a reply and do not see a response you assume that something did not work or there was an error.
I sended one reply for the 3rd time this morning.
Still not visible.
Why is there the delays or why nothing arrives at all?

Thanks in advance

Edit:   Ps. After I pressed send, the message came up.
>Message has been sent
This was not the case yesterday, so you have to assume that something is wrong!
