My Poor Guestbook is Under Massive Attack

My guestbook is at http://www.gilbertmatare.com/gilbertmguestbook/, I have spammers spraying it with all kinds of garbage. I have upgraded to 2.3 after my old 2.2 was defaced and hosed down by spammers. This guestbook business is just not worth all the trouble one has to do, to keep it away from idiots. Why is it so insecure in the first place??. Can someone suggest a trouble free guestbook instead of this one??
If you decide to help me please be explicit and dont use too much jargon. How do I patch this, I prefer if you dont send me to some page where I dont understand whats being said. I am very frustrated right now and ready to explode........LOL I am just a green noobie as far as php goes.

You could use the human verification mod you will find at the top of the GUESTBOOK FORUM or you could try my off shoot of Advanced Guestbook called Lazarus - www.carbonize.co.uk/lazarusgb.zip

open templates/form.php and find

from the human verification mod,
where do I find this file?, I will try it once I get home...........

As it states you will find it in the templates folder of the guestbook.

Okay I get a bunch of errors

When I try to add an entry I also get this.

Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /backup/gilbertm/public_html/gilbertmguestbook/lib/add.class.php on line 19

Gudos

you have some white space in your lang/english.php file. Probably after the ?>. How did you edit it? cPanel?

yes, C-Panel

The problem with cPanel is that it adds a new line to the end of the files it edits. This is why I always recommend downloading the file and editing it on your PC with a text editor. For this purpose I recommend PSPad which is a text editor with syntax highlighting and a built in FTP client.

Okay, some errors are now gone after using PSPad, like you suggested.
This is the one I have trouble with when I try to add an entry

Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /backup/gilbertm/public_html/gilbertmguestbook/lib/add.class.php on line 19

I had made a backup copy of my server english.php file. which I edited with PSPad, looks like it worked. I might have messed up all the others whilst editing in C-Panel. Can someone get me a copy ??

Open lib/add.class.php in PSPad and turn line numbers on (in View). Paste lines 18 to 20 in here.

var $bottestanswer = 'armadillo'; // this is the answer to the
question. It must contain no '
var $email = '';

var $bottestanswer = 'armadillo'; // this is the answer to the
question. It must contain no '

That should all be on one line.

I get this error

Parse error: parse error, unexpected T_ELSEIF in /backup/gilbertm/public_html/gilbertmguestbook/lib/add.class.php on line 198

Here is what line 198 looks like, starting from 196-205

196if ($this->name == "") { {
197return $this->db->gb_error($this->db->LANG["ErrorPost1"]);
198} elseif (strlen($this->comment)<$this->db->VARS["min_text"] || strlen($this->comment)>$this->db->VARS["max_text"]) {
199return $this->db->gb_error($this->db->LANG["ErrorPost3"]);
200} elseif ($this->bottest == '') {
201 return $this->db->gb_error($this->db->LANG["ErrorPost12"]);
202} elseif (strtolower($this->bottest) !=
203strtolower($this->bottestanswer)) {
204 return $this->db->gb_error($this->db->LANG["ErrorPost13"]);
205} else {

I appreciate all your efforts Carbo!!. Thanks a lot

Line 196 - { { should only be one.

Back in business, you are the man !!!!!!!!!!!!!!
