Hi,
When looking up
www.airsoft-hq.co.za/shop/register
I see no captcha, but when loading the Joomla registration
www.airsoft-hq.co.za/shop/component/user...istration&Itemid=478
, there is a v2.
Means that you have the Joomla captcha still active.
1. Disable the Joomla and all other captcha plugins, only the HikaShop v2 captcha plugin must be enabled and configured.
2. Also make sure the Joomla "Global Configuration" is set correctly.
3. Consider enabling and configuring the "Hikashop Registration Redirect Plugin".
