New Installation 4.3.4

Hello .. I have problems upgrading because not completed probably never question that the servers do not upload their waiting time.
The problems encountered in new edition installation 4.3.4 is when the customer go do check outs remove the message Sorry, service is temporarily unavailable. the same message comes out and when you go to see the abandoned baskets. knows someone help me; Thanks

What about server error logs? Do you see anything in the logs?

We forget this because I have spoken with officials and they could not raise the time out.

The problem with the mistake that leads to check Out (Sorry, service is temporarily unavailable)

same here... :(

Same here. With debug enable I get this
