500 error
The main causes for this error are the chmod not being
755, the file not being uploaded in ASCII or the path to
Perl being incorrect. If you're sure those are correct then
it could be a required module is missing. All our scripts
use our own perl module cosmic.pm do do a lot of routines.
Make sure this file is in the same folder as the script
you are trying to run. Check the script for use commands
such as "use cosmic;", each use command calls
a perl module, check with your host that all required modules
are installed. If all the modules are installed and available
then you've probably made a syntax error editing the variables.
Check the section below, 'editing variables'.
404 error
This means file file doesn't exist, so you've typed it
in wrong in your browser or you've uploaded to the wrong
place.
Editing Variables
It it important to be careful when editing variables. All
variables are in the form:-
$variablename = "value";
or
$variablename = 'value';
When editing make sure you do not remove the ; at the end
of the line, the $ at the beggining. Also make sure you
have an = in the middile, and either ' or " around
the value. When a variable uses the " notation, if
you want to include the symbols @, $, % or " the must
be receded with a \ to make \@, \$, \% or \". You do
not have to do this when the ' notation is used.
Updates are not taking effect
This means the data or output files are not being written
to. Make sure they are chmod 777, and are named correctly.
Relative or Absolute paths?
A relative path is the notation to get to a file or folder
from the scripts current location. An absolute path is how
to get to a file or folder from the root directory. Examples:-
/home/users/sites/cosmicscripts/cgi-bin/datafolder - This
is a absolute path
datafolder - This is a relative path
../public_html/datafolder - This is a relative path
With relative paths ../ means back a folder. This is very
useful when you need a relative path to a folder that precedes
the one the script it running in. So if you had your script
installed in:-
/home/user/cgi-bin/demoscript/scriptfolder (absolute)
and the data folder was in:-
/home/user/public_html/demoscript/output (absolute)
The relative path to the data folder would be:-
../../../public_html/demoscript/output (relative)
This means back 3 folders, then into public_html/demoscript/output.
All our scripts use relative paths, which are later translated
to absolute paths. Make sure you have entered any paths
as relative.
