Two (2) Zen cart website have stopped working due to change in PHP and Server. Topph.com - not loading at all Pingpongonline.com - loading but shopping cart is white page (after customer click add to cart) Upon checking the case, we understand that you have 2 issues with the domains topph.com and pingpongonline.com. Regarding the website topph.com, we noticed the website was using the older PHP version PHP 7.4, and the mysql_* functions were deprecated in PHP 5.5 and completely removed in PHP 7.0. Since you are using PHP 7.4, these functions are no longer supported. We have changed the PHP version from cPanel to 8.0. For your reference, I have attached a screenshot in this email. Also, we notice the error when accessing the website topph.com as mentioned below. We suggest you please check with the web developer to resolve the issue. ==== Fatal error: Unparenthesized `a ? b : c ? d : e` is not supported. Use either `(a ? b : c) ? d : e` or `a ? b : (c ? d : e)` in /home/gto/public_html/zc_topph/includes/application_top.php on line 84 ==== Regarding pingpongonline.com, we could not locate any error logs when we replicated the issue by accessing the shopping cart page. We suggest you kindly recheck your web code with a web developer to identify the exact issue with the code.
