SJ Filter for VirtueMart is not functioning. In admin area, in Categories and Manufacturers tab, it says;
Maybe your component (Virtuemart) has been installed incorrectly.
Please sure your component work properly.
If you still get errors, please contact us via our forum or ticket system

And it's not functioning in the site, only price is working.

The site is Joomla! 3.9.14, VirtueMart 3.6.10, Sj_furni Virtuemart template from you.

Hello,

All above modules has is a file in path : core\fields\sjvmcategories.php
So you need to simply change (near line 46 ):
if (!class_exists('VmModel')) {
if (defined('JPATH_VM_ADMINISTRATOR') && file_exists(JPATH_VM_ADMINISTRATOR . '/helpers/vmmodel.php')) {
require JPATH_VM_ADMINISTRATOR . '/helpers/vmmodel.php';
} else {
$this->error = 'Could not find VmModel helper';
return false;
}
}​
with below codes :
if (!class_exists('VmModel')) {
$vmpath_admin = $rootPath.'/administrator/components/com_virtuemart';
JLoader::register('VmModel', $vmpath_admin.'/helpers/vmmodel.php');
}
and find
protected function getCategories()
comment code
//VmConfig::loadJLang('com_virtuemart', true);
VmConfig::loadConfig();

Thanks
