It happened, the first "porting" problem reported to me by a user. Last week I moved my sites from a Windows 2000 box to Linux 8 running Apache 2.4. The move was about us painless as can be (with the exception of having to rename a few copies of application.cfm to Application.cfm). Today a user in the Netherlands informed me that one of my lesser used pages was throwing a error. The problem? Case-sensitivity, on Linux (well, any platform but Windows) is case-sensitive. Ugh! The moral of the story? Keep case of file names and their references consistent, even if you are running on Windows for now. Just in case.
