guestbook in html code, IP problem

I incuded a HTML code in my website (XHTML 1.0 Transitional//EN) to use the guestbook in the sidebar:

The guestbook does not show, I see a square where it should appear but within it says that the website can not be found. The explenation says: The IP address for the website you requested could not be found.

I checked the config.php and on line 47 it says:

I tried a lot of things but I'm stuck now.
Can anybody help me?

Hello wannabe, I will be happy to help you. Can you check to see if PHP is enabled on your website? Please create a file called "phpinfo.php", and put the following in it:

Upload it to your site and run it using your URL to see if you get a screen full of information.

Thanks,
Pete

Hi Pete,
PHP is on as I have also a contactform active on the website and it runs without problems.
I uploaded the phpinfo.php file as you mentioned within the guestbook files.

No luck. I see the same square but now it get in that field a message that it has internet connection problems. No connection.

Try accessing the guestbook directly outside the iframe and see if you can see it. Also disable the domain and IP checking.

Make sure all PHP files have a permission of 644 and all directories within it a permission of 755.

Hello Pete,
Aha, I can access the guestbook directly outside the iframe, no problem, also entering a message is no problem.
I disabled the domain and IP check in config.php
The php files all have a permission now of 644 , the folders and files within each folder have a permission of 755.
I read in the guidelines the data folder and it’s content should have a permission of 777?

Again in get a message in the sidebar, where I want to have the guestbook, that the IP address could not be found.

Please PM me the actual URLs (both to the page containing the iframe and the direct link to the guestbook without iframe) so that I can analyze the exact setting.

Pete
