Thread is cut and latest posts don't appear

The forum TelTalk.org (Invision) is working fine in general.

There is a technical error with this thread:
http://www.teltalk.org/t1487-soap-works-and-formats-questions

Posts 1 and 2 appear as they should.
Post 3 is cut.
Here ends the display of the thread.
Posts 4 and 5 don't appear at all.
The quick answer form and the administration buttons don't appear either.

Hi,

Try this as it can sometimes solve display bugs.

ACP --> General --> Forum --> Configuration --> Resynchronize Forum --> Check Box Yes --> Save

If it doesn't work the first time then try it once more as it can sometimes take two tries. If it doesn't work then please let us know.

Thank you for the advice.

I resynchronized the forum twice, but no change has happened.

Meanwhile I know the reason causing the problem:

In posts number 3 and 4 the following code appears (without marking it as code):

Code:

... as the <title> and <h1> tags ...

I need to delete post number 3 in this thread, too:
http://www.teltalk.org/t1488-soap-works-and-formats-questions-shareactions-2

Due to the problem I don't have access to these posts. How can I delete them to repair the situation?

I would like to repair the two broken threads.

I'm afraid I can't do it myself as forum administrator.

Is it possible to repair it with access to the database?

Try disabling HTML for your entire forum then go in and delete the posts or edit the codes in question out.

To disable HTML go to AP>>General>> Configuration>>

On that page under "Allow HTML" select "No".

That's what I needed. Thank you very much.

Problem solved.
