What do you see in error logs for 503 errors? Do you try to create an order from the admin panel when this error occurs?
What do you mean by "save"? Do you create new order in the admin panel?
Hi, thank you for your reply. I did not see the logs 503. I don't know how. :-)
Yes I was try to add a new product from admin panel. When finish, I clicked I on save (or save and close) and the error page appeared. I don't know if there was anything wrong with the permission but I added lot of products before without any problem.
