There is a error after upgrade

-- url of the page with the problem -- : www.pianyifa.com
-- HikaShop version -- : 4.3.0
-- Joomla version -- : 3.9.15
-- PHP version -- : 7.4.5
-- Error-message(debug-mod must be tuned on) -- : 0 - syntax error, unexpected 'if' (T_IF)

Today I upgraded hikashop to 4.3.0. Unfortunately there was a error when click add to cart button after upgraded.
Error info:
0 - syntax error, unexpected 'if' (T_IF)

What is the problem? Thanks!

Hi,

Turn off the "add to cart legacy" setting under the Advanced tab of the Hikashop configuration and it will work.

Hi,

Now, to be able to fix the issue, we would need to know the full error message and not the truncated one you have there.
For that, you can activate the "error reporting" and "debug mode" settings of the Joomla configuration and try again. The error message should now contain the file and line number of the problem.

0 - syntax error, unexpected 'if' (T_IF)

Hello,

You have to re-download the HikaShop package on our website and install it on yours ; the hotfix has been published one week ago.
