CAPTCHA Malfunctioning...Missing Letters? [Solved]

registered · Posted: Mon Mar 19, 2007 4:39 pm

I have the $gfx_chk = 6. This morning from work I went to log into admin, and I noticed that the security graphic had what looked like a space in the letter sequence. So I just typed the letters I saw. That didn't work. The next one had the same problem. So I typed a space where I thought there would be one, but that did not work either. The next one had all the letters so I got in.

And then I just had a new user tell me he ran into the same thing. It took him several tries before he got one with all the letters.

Any ideas? Just tell me where to look and I can help debug this.

I checked my error logs and here is something interesting:

Code:




[client x.x.x.x] PHP Warning: imageftbbox(): Could not read font in /usr/local/plesk/apache/vhosts/xxx.com/httpdocs/includes/class.php-captcha.php on line 298, referer: http://www.xxx.com/modules.php?name=Your_Account

Looks like a bad FTP. I had some font files in includes/fonts with 0 size. I'm really not trusting FileZilla anymore...

Hhhmmmm... That is odd. I have never had issues with FileZilla, but I have seen this issue of the "space" before and never knew what caused it. I would just refresh my page until I got a complete captcha. I'll have to check the respository to make sure we do not have any 0 sized files.

I have checked the repository and no 0 sized files. So, I guess that doesn't solve my issue of intermittent problems in a local XAMPP environment. I have never had the captcha fail on a live production site, only on my local XAMPP.

Well I certainly did not have any 0 sized font files in my archive of 2.10. They just ended up that way somehow when I ftp'ed them to the server. I was probably premature in marking this "solved", but time will tell. So far so good.

Mmmm... maybe worth mentioning here: sometimes I do not get a CAPTCHA picture at all... After a few F5's or refresh-button clicks it shows up again...

I will also check my logfile a.s.a.p. and if any anomalities are found, I will post it.

klaafstra99, I have only seen this happen in my local Windows XP based system. I have yet to experience this personally on my actual server. What kind of set up are you seeing this happen on?

Indeed (I am forced to use) a Windows XP system.

My software setup:

Window$ XP Pro

RN 2.10 running on Appserv 2.5.8 (This is a WAMP solution of Apache 2.2.4, MySQL 5.0.27 and PHP 5.2.1.

Check your error logs.

The location and how to get at your error logs are host dependent. Ask your host if you don't know.

There is another thread about this going on, which I started because this one has the status of 'SOLVED'.

Ah no worries your post did help me though by linking to the yoursite/images/captcha.php?size=normal

i got my error !

Code:

Fatal error: session_start() [<a href='function.session-start'>function.session-start</a>]: Failed to initialize storage module: user (path: /tmp) in /clientdata/www/com/p/phoenixechelon.au.com/includes/class.php-captcha.php on line 48

Which is related to my other previous problem of sessions here http://www.ravenphpscripts.com/posts13232-highlight-.html
