Hi all, I'm running OTRS 2.4.7 on Windows Server 2003 SP2 with the customer back end pointing to an LDAP directory on Active Directory. Everything was working fine but when I installed the iPhoneHandle package (iPhoneHandle-0.9.4.opm via the OTS interface) all I could get (from the iPhone or a normal browser) was a 500 error. In the Apache error.log file I got; [Tue Aug 10 09:32:19 2010] [error] [client nn.nn.nn.nn] (OS 3)The system cannot find the path specified. : couldn't create child process: 720003: json.pl [Tue Aug 10 09:32:19 2010] [error] [client nn.nn.nn.nn] (OS 3)The system cannot find the path specified. : couldn't spawn child process: C:/Program Files/OTRS/OTRS/bin/cgi-bin/json.pl I checked the package and it was all showing as status OK in the package manager, I checked and the file c:\Program Files\otrs\otrs\bin\cgi-bin\json.pl exists, so assumed it was something other than the file just not being there. I checked json.pl and the first line pointing to perl was #!/usr/bin/perl -w. I compared it to my index.pl and substituted the line from there; #!C:/PROGRA~1/OTRS/StrawberryPerl/perl/bin/perl.exe -w .. and now everything is working fine. I might have been dumb not to check this first, but just in case anyone else had the error I thought I'd post it up as I'm sure everyone's dying to get the iPhone app up and working!
