Cannot see order pages randomly

[ferramentaacasa]

Hi, we have PS 1.6.1.11(I will update soon) and we had some issues with order page in BO. We can see orders list but we cannot see any order detail when trying to open an order.

See the screenshot attached.

 

It happened few months ago, 2 or 3 times, with 1.6.1.8 and 1.6.1.9(not solved with PS update). I tried to restore all files on the server without solving, we solved restoring the entire DB to the previous date. All times it happened when no one is working on the website(in BO), the order page in BO is the first use of our website at the moment and, for example, it was working 3 days ago and not working today(I see the page reported in the file attached).

 

Tried to disable all non-official modules without solve, the only way is to restore the entire DB.

 

Is someone knows what we can do?

Thank you.

CSS styles are not loaded. It could be a server issue. I vote for server timeout or overloaded server during huge traffic.
