i think i found where the problem is:

SEO Urls are cusing the file to be renamed:
captcha_img.php.html?zenid=1e4a50...
it's adding the extra .html after the file ext. i'll try to find a way to remove it

have you fix it, I have the same problem, some one help me, thanks, how to fix this problem

You understood me correctly.. It uses CSS and a hidden field to trap the bots.. Fools the bots into thinking the form is filled in correctly..

I am just wondering if there is any way to check this is working ? - I am using 1.5.1 - but still get some contact form spam - are there any settings anywhere in Admin to set or adjust ?
Many Thanks.

I'm sorry, I did not quite understand. You're using 1.5.1 and css spam protection? And still get spam? Want to try a graphical captcha?

Honestly this support threead isn't really the RIGHT place to have an in depth discussion of the built in spam deterrent.. Open a new thread or better yet do a forum search for related topics (because this HAS BEEN discussed before)

Very sorry - my apologies - I did actually do several different searches - but obviously didn't use the correct search terms - as I didn't find anything explaining the built in spam deterrent...

You can see the alterations for this discussed in a forum thread about "CSS/PHP AntiSpam solution". the thread is long and has many suggestions, and the code built-in to v1.5.1 is a bit tidier.

can't get this to work.. installed all the files and ran the sql query fine. most pages work but the registration page does not show the captcha AND in the admin there is nothing under 'configuration' that says 'captcha'. i check the configuration-group table and the new entry is there for 'captcha' but it still doesn't show on the pull down menu for 'captcha'. i can't take a screen shot because as soon as i move my mouse from the 'configuration' tab to capture the screen, the pull down disappears.

looks like the sql file included with this download is missing sql statements?? it doesn't add anything to the table 'admin-pages'.

here is the file:

SET @configuration_group_id=0;
