Hello,
I’m trying to use a module on Prestashop 1.6.1.13 called Store Commander. It works very nice on other installs, but on the site with theme SNS Nova, I have the following error:

Fatal error: Uncaught Error: Call to a member function addJquery() on null in /var/www/vhosts/moteurselectriques.fr/devframework3/modules/snsnovatheme/snsnovacore.php:63 Stack trace: #0 /var/www/vhosts/moteurselectriques.fr/devframework3/modules/snsnovatheme/snsnovacore.php(37): SNSNovaCore->addModMedia() #1 /var/www/vhosts/moteurselectriques.fr/devframework3/modules/snsnovatheme/snsnovatheme.php(40): SNSNovaCore->__construct() #2 [internal function]: SNSNovaTheme->__construct() #3 /var/www/vhosts/moteurselectriques.fr/devframework3/Core/Foundation/IoC/Core_Foundation_IoC_Container.php(124): ReflectionClass->newInstance() #4 /var/www/vhosts/moteurselectriques.fr/devframework3/Core/Foundation/IoC/Core_Foundation_IoC_Container.php(157): Core_Foundation_IoC_Container->makeInstanceFromClassName(‘snsnovatheme’, Array) #5 /var/www/vhosts/moteurselectriques.fr/devframework3/Core/Foundation/IoC/Core_Foundation_IoC_Container.php(170): Core_Foundation_IoC_Container->doMake(‘snsnovatheme’, Array) #6 /var/www/vhosts/moteurselectrique in /var/www/vhosts/moteurselectriques.fr/devframework3/modules/snsnovatheme/snsnovacore.php on line 63

Could you please advice me on what to do to resolve it ?
I know it’s an ancient theme but still working so far !

Thanks in advance,
Best Regards,
Stephane
