Well, it doesn't make any difference by removing the <tr> tag.
I get the following error:
Code:
Fatal error: Smarty error: [in ./customer/main/customer_details.tpl line 28]: syntax error: mismatched tag {/if}. (Smarty_Compiler.class.php, line 2277) in C:\XAMPP\xampp\htdocs\shop\Smarty-2.6.9\Smarty.class.php on line 1088
Edit: My live shop is on a apache server. But I'm doing my template editing and modifications on a test server on my own computer, so that my live shop won't be interrupted.
