Re: Debug build on a live server?
It's several decades since my semi-amateur coding days. Even then I used two copies of the s/w. One for doing the testing and one that I'd only amend after I'd got the test version working.* These of course were not a on a server. Deployed to stand alone PCs.
*OK yes there were a couple of times when the amended version didn't run properly. I think I always was able to find the typo with a quick look.
