403 Error On Submit of CKEditor Data

Hi Guys,

I hope somebody can help me out.

I have integrated ckeditor and ckfinder onto a website and they both appear to be working correctly until, well that was until I tried to enter in more than one line of information within the ckeditor.

when I tested it I just placed one sentence into the ckeditor and posted the form that it resided in, and my php code picked up the HTML and saved it successfully to the MySQL database, so I was under the impression it was working.

As soon as you enter a second paragraph into ckeditor and try to post the data then I get a 403 Forbidden error displayed. This is really strange as I can't tell why it would be doing this.

So for example if I sent the following;

<p>This is a test paragraph</p>

then it would save correcly without the 403 error, but if I sent;

<pThis is a test paragraph</p>
<p>and this is the send paragraph</p>

then on posting the form I would get the 403 error.

Can anybody shed any light on this?

For info I have access to cPanle on the server but other than that I can't change any settings on the server.

I am not sure if this is a permissions problem, a ckEditor problem or what?

I have 611 permissions on the php file, but I don't think this is the problem as it only occurs when the data is over a certain length.

Thanks for your help in advance.
