I dont see a section this would fit in exactly and ive searched.. old and blind? perhaps lol

How can i change to the captcha you guys use on here (just numbers in a box) from the default numbers and letters with squigly lines? I got some members who cant get the captcha right time after time Rolling Eyes

........... and feel they would have a better chance (and me less phone calls!)

Thanks guys! Very Happy

Don't know that you can change it. You can turn it off entirely though in config.php. The instructions are right in the file.

Edited: corrected "rnconfig.php" to "config.php"

The recipe is in includes/class.php-captcha.php Smile

Edit the setting define('CAPTCHA_NUM_LINES', 70);

To get rid of all lines, change the 70 to 0

define('CAPTCHA_NUM_LINES', 0);

Ill try that as soon as i can, just to confirm though.
This would change the captcha with all the squigly lines to the same as the one you guys use here? with the numbers only in a grid?

No it won't make it the same. The captcha used here is the old style, which was easier to crack by bots.

Removing the lines as Raven said should make it easier to read, but will of course make less secure.

If your users are having trouble reading it surely it is a good thing because then the bots won't be able to crack it either. Wink

Just a note on Jake's comment "but will of course make less secure". It is less secure only in regards to auto scanning the image. The old style, used here, is/was less secure because the method for creating it can/could be predicted. The new one, with or without the background noise, is no longer predictable Wink

Yes you are right Raven, sorry I should have made that clearer.

For the gazillionth time .....

This site does not use RavenNuke(tm), per se. This site was built on v6.5 and was upgraded over the years to an extremely customized v7.6. The code then became the foundation for RavenNuke(tm) v1.00.00 released 24-Nov-2005. I have so many customizations to this site, custom code/modules/blocks, different rewrite rules, etc., that it's not really feasible to upgrade to RavenNuke(tm) nor needed, other than to stop having to answer this same question over and over ROTFL

. This site has all the security of RavenNuke(tm) but just not the styling. Sometime, before I die (maybe), this site may eventually be a visible RavenNuke(tm) site. So, the appearance is but a facade; the structure is very much RavenNuke(tm) where needed Wink

. And, since the old style captcha is now secured there's really no reason to fix what isn't broke.
