Captcha no work

Hi, I have a website with HikaShop and I have a problem.
Once in the shopping cart, when I go to register, the component asks me for a captcha, but no matter what I write, I take it for valid.

Joomla 2.5.14
Recaptcha is installed but I think it isn´t hikahop

Hi,
You should then use the ReCaptcha on forms plugin which is the Hikashop captcha plugin.

Hi,
The ReCaptcha on forms plugin is enabled, but not working.
If I leave the captcha blank, or anything I write, the captcha take it for good.

Ok, so can you give me a link to the page where you are having your issue so that I can test it myself ?

I also have a problem with Captcha but only on one page: test.safka.co.nz/component/users/?view=reset
captcha works fine on other pages but on this one the image is not displayed at all, do you know why?.
Joomla 2.5.6. Hikashop business 2.0.0.

I don't know where this page is getting this code from, can you tell me where I can fix this?

<label id="jform_email-lbl" class="hasTip required" title="" for="jform_email">
Email Address:
<span class="star"> *</span>
</label>
</dt>
<dd>
<input id="jform_email" class="validate-email required" type="email" size="30" value="" name="jform" aria-required="true" required="required"> </dd> <dt> <label id="jform_captcha-lbl" class="hasTip required" title="" for="jform_captcha"> Captcha <span class="star"> *</span> </label>[email]" aria-required="true" required="required">
</dd>
<dt>
<label id="jform_captcha-lbl" class="hasTip required" title="" for="jform_captcha">
Captcha
<span class="star"> *</span>
</label>

ok, found the issue
if someone else has the same problem, it is not enough to disable Joomla Catchpa but you also need change the User Manager / Options / Captcha to 'None selected'
