Dear,

I just change as follows:
in file modules/snssmartblog/.tpl
change

require_once (_PS_MODULE_DIR_.'smartblog/classes/SmartBlogPost.php');
require_once (_PS_MODULE_DIR_.'smartblog/smartblog.php');

to

if(Module::isInstalled('smartblog') != 1){
	require_once (_PS_MODULE_DIR_.'smartblog/classes/SmartBlogPost.php');
	require_once (_PS_MODULE_DIR_.'smartblog/smartblog.php');
}

Thank you!
