Issues with Upgrade - 'Error: Could not load model total!

Hi All,

Was using opencart 1.5.6.1 and am trying to upgrade to the latest version of opencart.
url: http://www.burleyarms.co.nz

After following opencarts upgrade documents page step by step i got as far as the opencart upgrade menu before the success page where it tell you to remove install directory. when i press the continue button to go to the upgrade complete page with the option to go to the store or admin i got a blank page with the following error

Can anyone please help elaborate on this and a fix please:

Fatal error: Uncaught exception 'Exception' with message 'Error: Could not load model total!' in /home/burleyar/public_html/system/engine/loader.php:169 Stack trace: #0 [internal function]: Loader->{closure}(Array, Array) #1 /home/burleyar/public_html/system/engine/proxy.php(25): call_user_func_array(Object(Closure), Array) #2 /home/burleyar/public_html/catalog/controller/common/cart.php(37): Proxy->__call('getTotal', Array) #3 /home/burleyar/public_html/catalog/controller/common/cart.php(37): Proxy->getTotal(Array) #4 [internal function]: ControllerCommonCart->index(Array) #5 /home/burleyar/public_html/system/engine/action.php(51): call_user_func_array(Array, Array) #6 /home/burleyar/public_html/system/engine/loader.php(24): Action->execute(Object(Registry), Array) #7 /home/burleyar/public_html/catalog/controller/common/header.php(129): Loader->controller('common/cart') #8 [internal function]: ControllerCommonHeader->index(Array) #9 /home/burleyar/public_html/system/engine/action.php(51): call_user_func_array(Array, Arra in /home/burleyar/public_html/system/engine/loader.php on line 169

Have a sneeking suspension that it is the theme possibly as can successfully load admin and under the store settings, only the default theme option is available. but could be completely wrong.... still learning


Really appreciate your help asap

I had the same error message. In my Config.php file I found there was a mixture of '\' and '/' in the paths.
Changed all the '\' to be '/' and it worked :-)

Thats rely weird,
definateltly will give it a go.
Did you delete the configs from the new version and are you refering to the "/" being around the wrong why in the original configs that you left on the server.

Thanks so much for your comment

Had a look at both config.php files under public html and admin and it appears the both files only contain "/" and no "\"
