Firefox register.php with CAPTCHA issue

It's not a PunBB thing, your server seems to be sending this in the request

You'll have to see what's causing that

I don't think he does, since the other pages work fine

And all Opera shows is a cute little box with the word "Image" inside.

I've changed the name of the topic since its nothing to do with register.php in its normal configuration.

"CAPTCHA" is an acronym for "completely automated public Turing test to tell computers and humans apart".  It is what is on the registration form on the website in question, but doesn't always have to be programmed in php.  See thr following wikipedia entry for more information

http://en.wikipedia.org/wiki/Captcha

As you can see, there is a lot of programming languages that you can make a CAPTCHA for.

Yes, I am in total agreement.  There were a lot of odd tags in the source.  But that's just XHTML.  XHTML = ODD

This is also true, but I think it is safe to say that there is something definitely weird/fishy with the image (CAPTCHA) code here.

EDIT:
This image on the server might be why Firefox refuses to show the page correctly:

I'd love to gog back to 1998.  But I can't - now back to the main issue.

I've looked over the sorce of the file, and it does seem to be a CAPTCHA, but one that doesn't rotate like many of the ones that we see today on registration forms.

Here is the link to the "CAPTCHA" image on the server.

When looking at the source, and the result of the page, I would still guess that it for some reason is being read as an image (possibly due to the code within img.php).

"The only odd markup is that stuff somebody has added in the announcement box and a totally pointless table. Unclosed tags and, I almost can't believe it, tags in uppercase. I guess there has been a time warp and we've gone back to 1998."

The only thing editted by myself is the _bottom_ of the reggy page, and recently (like, this morning) I modded the top nav thing to gen the "PM" link. The image/png header has been removed from the reg*.php so I dunno why you're still getting it. Possible cache issues, me senses.

The stuff in the announcement box .. I can't explain. I've not touched it (ask Jacob)

My HTML style is very old, yes (I left for better things 1.5 years ago) but it's worked for me so far. The tags are in upper case because they are 'supposed' to be. From what I can see, there're no unclosed tags around where I have editted the reg page, so that again is out of my hands. The tables are there to format the page. I couldn't use anything else because it formatted incorrectly. Using <div> tags caused them to line up next to each other. Same for breaklines. I threw some empty tables in because they're the only sure-fire way of knocking everything onto the next line. I personally hate any form of new, 'this is so great' HTML including div, etc. because they seem.. wank. That could be because I don't understand them.. and to be 100% honest, I don't want to Bigger things on my plate ATM.

The bot/script check was coded by myself. It's all standard stuff. The reg page calls for an image (img.php). The img.php page generates a random number, creates an image and writes the text to it. Obviously it uses sessions. The page itself is fine. Everything is there, in the right order, closed properly, and it works.

To say my PHP is the cause of the problem is a bit off the mark. We know the problem is browser-specific.. meaning it's a problem with what the browser is handling. The browser only handles 2 things. 1, headers. 2, HTML/JS. PHP is server-side, therefore.. it never makes contact with the browser. If there was an actual PHP error, the PHP parser would say so... but it's not. So, the problem has absolutely _nothing_ to do with my PHP. I can safely say that. I am guessing the problem is related to the way firefox/opera handles different bits of HTML/JS, or possible incorrect headers (could be the image/png thing.. but like I say, that's gone now so that bit is out of my hands)

Dom (admin at the site) did report that he was getting other errors in FireFox. Before we made any mods to it. That being, the nav bar at the top didn't change, whether he was logged in or not. It continued to display the register/login links.

I'm not just being pedantic or flippant about the markup. PunBB is coded in XHTML 1.0 Strict. The existence of the strict doctype puts browser into standards compliance mode. That means any markup which is not xhtml strict could potentially cause problems.  In many cases it doesn't but if you use non valid markup it can make it much more difficult to track down whats causing errors.

XHTML, unlike HTML, is case sensitive. All tags and attributes must be in lowercase. It's not a question of coding style, its part of the specification. As for unclosed tags, the <img>, <br> and <input> tags are unclosed. They should be <img />, <br /> and <input />.

The usual cause of the login problem is cookies being disabled or blocked. Also see http://punbb.org/docs/faq.html#faq2_5.
