Multiple "Smarty" based errors after fixing an template - php

Question

This is a rather misterious case. My "Prestashop" based website was working flawlessly, until this error popped up without editing anything for days:
Fatal error: Uncaught --> Smarty Compiler: Syntax error in template
"/themes/default-bootstrap/product-list.tpl" on line 213 "{/foreach}"
unknown tag "foreachclose" <-- thrown in
/tools/smarty/sysplugins/smarty_internal_templatecompilerbase.php on line 213

Someone pointed out that 3 lines of the mentioned file were missing. After I added them I got this array of errors popping up on my website but it was at least loading again:

I now had the idea of installing Prestashop again and copying the smarty plugin into the directory again to simply hope that it will fix the problem. It seems quite corrupted or something like that since I absolutely didn't touch mentioned php files. I also disabled all non-prestashop modules to verify that it wasn't caused by them.

Answer 1

Those three lines:
{math equation="(total%perLine)" total=$smarty.foreach.products.total perLine=$nbItemsPerLine assign=totModulo}
{math equation="(total%perLineT)" total=$smarty.foreach.products.total perLineT=$nbItemsPerLineTablet assign=totModuloTablet}
{math equation="(total%perLineT)" total=$smarty.foreach.products.total perLineT=$nbItemsPerLineMobile assign=totModuloMobile}
Should be placed after the {foreach} in your template:
{math equation="nbLi/nbItemsPerLine" nbLi=$nbLi nbItemsPerLine=$nbItemsPerLine assign=nbLines}
{math equation="nbLi/nbItemsPerLineTablet" nbLi=$nbLi nbItemsPerLineTablet=$nbItemsPerLineTablet assign=nbLinesTablet}
<!-- Products list -->
<ul{if isset($id) && $id} id="{$id}"{/if} class="product_list grid row{if isset($class) && $class} {$class}{/if}">
{foreach from=$products item=product name=products}
{math equation="(total%perLine)" total=$smarty.foreach.products.total perLine=$nbItemsPerLine assign=totModulo}
{math equation="(total%perLineT)" total=$smarty.foreach.products.total perLineT=$nbItemsPerLineTablet assign=totModuloTablet}
{math equation="(total%perLineT)" total=$smarty.foreach.products.total perLineT=$nbItemsPerLineMobile assign=totModuloMobile}
You placed them before the {foreach} while calling total=$smarty.foreach.products.total so total is undefined and math throws an error.
