Error 500 when I click Add to cart

-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.6.5
-- PHP version -- : 5.6.30
-- Browser(s) name and version -- : Chrome Version 57.0.2987.133 (64-bit)
-- Error-message(debug-mod must be tuned on) -- : syntax error, unexpected '?'

This happens on the Checkout Page. Any idea what can cause this? I thought it was my template but I tried with Protostar and same problem.

syntax error, unexpected '?'
.../templates/protostar/html/com_hikashop/address/address_template.php:9
4 {address_company}
5 {address_title} {address_firstname} {address_lastname}
6 {address_street}
7 {address_post_code} {address_city} {address_state}
8 {address_country}
9 <?php echo JText::sprintf('TELEPHONE_IN_ADDRESS','{address_telephone}');?????????????????>

Thank you for your answer.

I have deleted customization and still have the same error.

Any idea?
