Hi Alessandra, The access command is a generally installed "user" command. Of course, since we wrote the script we've found that "generally" is quite relative and many sites have not intalled this command. All it does is check the access permissions on the file. It should be replaced by the test function which would provide more limited error checking but still allow the script to verify that all the required files are present and either writable or executable. The quickest and easiest solution is probably to comment out the command and always return success. We'll be changing that script in a future release.
