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 :lol:

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.

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)

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;
SELECT (@configuration_group_id:=configuration_group_id) FROM configuration_group WHERE configuration_group_title= 'CAPTCHA' LIMIT 1;
DELETE FROM configuration WHERE configuration_group_id = @configuration_group_id AND configuration_group_id != 0;
DELETE FROM configuration_group WHERE configuration_group_id = @configuration_group_id AND configuration_group_id != 0;

INSERT INTO configuration_group (configuration_group_id, configuration_group_title, configuration_group_description, sort_order, visible) VALUES (NULL, 'CAPTCHA', 'CAPTCHA Configuration', '1', '1');
SET @configuration_group_id=last_insert_id();
UPDATE configuration_group SET sort_order = @configuration_group_id WHERE configuration_group_id = @configuration_group_id;

INSERT INTO configuration (configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, date_added, use_function, set_function) VALUES 
(NULL, 'Code Length', 'CAPTCHA_CODE_LENGTH', '6', 'Verification Code length', @configuration_group_id, 1, NOW(), NULL, NULL),
(NULL, 'Image Width', 'CAPTCHA_IMG_WIDTH', '240', 'CAPTCHA Image Width', @configuration_group_id, 2, NOW(), NULL, NULL),
(NULL, 'Image Height', 'CAPTCHA_IMG_HEIGHT', '50', 'CAPTCHA Image Height', @configuration_group_id, 3, NOW(), NULL, NULL),
(NULL, 'Chars minimum size', 'CAPTCHA_CHARS_MIN_SIZE', '0.6', 'Chars minimum size (1.0=Image Height)', @configuration_group_id, 4, NOW(), NULL, NULL),

(NULL, 'Image Type', 'CAPTCHA_IMG_TYPE', 'png', 'CAPTCHA Image Type', @configuration_group_id, 10, NOW(), NULL, 'zen_cfg_select_option(array(\'png\', \'jpeg\', \'gif\'),'),

(NULL, 'Links Submit page', 'CAPTCHA_LINKS_SUBMIT', 'true', 'Activate Validation on Links Submit page', @configuration_group_id, 24, NOW(), NULL, 'zen_cfg_select_option(array(\'true\', \'false\'),'),
(NULL, 'Write Review page', 'CAPTCHA_REVIEWS_WRITE', 'true', 'Activate Validation on Write Review page', @configuration_group_id, 25, NOW(), NULL, 'zen_cfg_select_option(array(\'true\', \'false\'),');

how does it do this?? i don't see the 'hidden fields' in the tpl file..

After several years I'm finally upgrading and now know I don't need this plugin.
However I understand it has used an SQL patch into the database when I originally installed it and wonder if anyone has advise on a safe uninstall process before or after the upgrade process (I'm moving from 1.3.9h to 1.5.5c).

Obviously the .php and other files can be omitted, so it's just the SQL patch that has me puzzled.

SQL... a safe uninstall process

My Error. Ignore the above... Found the uninstall.sql patch in the original 6 year-old folder. :blush:
