Hi,
it seems that hikashop is not compatible with SecurImage Captcha Plugin
Is also
it seems that SecurImage Captcha Plugin is not compatible with hikashop
HikaShop 2.x is not using Joomla "captcha" plugins because that system is not compatible with Joomla 1.5.
It is mostly why the HikaShop recaptcha plugin is a system plugin and not a "captcha" one.
That decision has been made some years ago (before Joomla 3) in order to also provide captcha to Joomla 1.5 websites.
But with HikaShop 3 ; we plan to add the support of "captcha" plugins ; there will be also new triggers which will simplified the integration.
But for HikaShop 2.x the integration has to be made in the captcha plugin, not in the component.
Regards,
