Problem With 4.310 And Php 7

Getting homepage ok but get this error when clicking on a link , any ideas what might be wrong , if I switch PHP to less than 7 I get just a white screen and no error showing . I have site in dev mode for errors

PHP Fatal Error

Error at

app/functions/fn.images.php, line: 646


Have tried using the them CS Cart comes with and get same error / similar just paths different where it mentions ' vivashop '

Did a bit more testing and it appears other links work such as contact us about us etc , it's just the categories and product listing where this error is occuring

Think I am sorted looks to be working now GD was enabled but not for PHP 7 only 5 ...heres hoping all ok now


Are your solved the problem?

4.3.10 + energot using Imagick don't display pictures. changing to GD looks to be working

mod_fcgid: stderr: PHP Fatal error: Call to a member function open() on a non-object in /home/xxx/public_html/app/functions/fn.images.php on line 646

$image = $imagine->open($src);
