Hi,
i wanna know this problem come from hikashop ? or gantry 5 framework ? or my template !!! this is broken my mind because ( i receive error 404 without any error massage ) so i cant understand this 404 coming from where bro
Maybe I wasn't clear enough. The problem is not in HikaShop's code, nor in HikaShop's settings, nor gantry 5 nor your template. The problem is with the setup of your server or the htaccess file.
If the htaccess.txt file is not renamed to .htaccess you can't remove the index.php in the URLs, or the URLs will all display 404 errors.
And on some servers, additional steps need to be made in the server configuration to support the removal of the index.php as explained in the link I gave before:
docs.joomla.org/Enabling_Search_Engine_Friendly_%28SEF%29_URLs
If you renamed the htaccess, and followed the steps there and it still doesn't work then you missed something with the instructions there, or something else on your website messed with the htacccess. For example, if you manually empty the htaccess file, even if you rename it to .htaccess, it won't work. There are some components, like adminTools, which can modify the htaccess based on how you configure it. So it's possible you might have messed up that file without knowing it. I would recommend comparing the file with the default htaccess file of a Joomla install package.
In any case, your issue is between Joomla and your server. That's why I told you to ask on forum.joomla.org
The problem is not in HikaShop and our support is only for HikaShop so we can't help further on that index.php issue.
