Layout on product page -- shows layout not found 500 in front end

-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.5
-- PHP version -- : 5.5.13

Hi,
I set the product layout in the configuration/display. But in the front end product detail page I got “500 not found " as the screenshot in the attachment.
In my developing environment, this can be shown properly, but when I copy it to server, I got the error message.
I've set joomla configuration to development, but nothing more information was shown.
Could you give me the advice how to find the cause of this, Thanks.

Best regards

Hi,
I've solved the 500 problem mentioned in the previous post, but there is still problem remained.
My program is modified from tabular.
And I found if I put <?php exit; ?> behind the original code (the javascript code), it will shows the result, or it shows a blank page.
but the Chinese characters are all shown wrongly.
I attached with the screenshot of it, and I hope this could help a little.
The same file in my local environment shows same result as in the server.
If I remove the code, my local shows correctly, but the server shows an empty page.
Other layout file are all OK , except this one.
Could you direct me what could possibly wrong. Thanks.

Best Regards
