Hi,
If you want to fix the problem, you have to not display the "aiContactSafe" form into the HikaShop form.
So, you have to display the "hikashop_product_bottom_part" part, outside of the form.
First, edit the view "product | show_default".
Select the end of the view, since:
<div id="hikashop_product_bottom_part" class="hikashop_product_bottom_part"> ....
And cut it (copy and delete).
Then edit the view "product | show".
Paste the content after the block:
<input type="hidden" name="ctrl" value="product"/>
<input type="hidden" name="task" value="updatecart"/>
<input type="hidden" name="return_url" value="<?php echo urlencode(base64_encode(urldecode($this->redirect_url)));?>"/>
</form>
At this moment, the "hikashop_bottom_part" will be display outside of the hikashop form. So the aiContactSafe form will be outside and will not generate conflicts.
It will work in your case but it could not work in order cases. If there is useful information in the bottom part, they will be not include in the form data so it can generate problems.
In your case, you just have text and the contact form, so it will not create problems, just fixing some.
Regards,
