Cant Open Old Orders

Store Builder Questions
1

I just imported my database from 2.2.4 to 4.0.3 (multi-vendor). Everything seems to be ok except for the fact that I can’t open most of the old ‘completed’ orders. I’m getting the message below



503 Service Unavailable



[color=#000000]The server is temporarily busy, try again later![/color]









I have no problem opening new ‘completed’ orders. Any idea?

I forgot to mention that this happens when viewing the orders from the storefront and admin panel
