It's weird,
Do you tried on your local computer, because I tested the lastest release and I have no problem.
Do you use Cpanel ? If yes you can install via Cpanel ClicShopping, it's automatic.
Note . All the script is called on CDN, If you have no connection with internet, you wil have a problem. I suppose it's to reduce the code by the developers,
Also, you can try something,
Find this function and put in comment these elements, One time I used another software with a lot code line on the same domain and I have been a problem
/**
* Calculate the size of a directory by iterating its contents
* @Access public
* @Return size if the directory
*/
Public Static function getDirSize(): string
{
/*
$path = CLICSHOPPING::getConfig('dir_root', 'Shop');
$path = rtrim(str_replace('\\', '/', $path), '/');
$bytestotal = 0;
$path = realpath($path);
if ($path !== false && $path != '' && file_exists($path)) {
foreach (new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($path, \FilesystemIterator::SKIP_DOTS)) as $object) {
$bytestotal += $object->getSize();
}
}
*/
$bytestotal = '';
return $bytestotal;
}
