can anyone please help me please?
Generally this error occurs if you have used sales_order_place_after event in which some thing is wrong, try to debug each and every line.
For that checkout page error, you need to check the log files. you can find errors in these files easily.
var/log/debug.log
var/log/exception.log
var/log/system.log
If you are using ubuntu system so just run below command so it will load all var/log files errors on the terminal.
tail -f var/log/*
