>> Firstly it is not using locking
Yeah, that's right. Might this be an issue? I've never worked with this Module before.

>> secondly it performs no error checking (eg. the return values from retrieve and particularly store are never tested)
On the "Userlist" we check if the Perl-Storage File exists. Then we get all userids from the CMS and we check if they exists in the Perl-Storage. If yes show it's data otherwise we display a fixed string. 
if ( $storage->{$id} ) {
  # show userid + timestamp
} else {
  # show userid + "never logged in"
}

On the "Useraction" we only check if the Perl-Storage file exists. Since this kind of system is only adding/overwriting data and not deleting anything we would add an entry to the Perl-Storage if it's existing otherwise overwrite it.

I just read in the documentation "The routine returns undef for I/O problems or other internal error, a true value otherwise. Serious errors are propagated as a die exception." so I'll add proper error checking now.

>>it would be good to know which version of Storable your environment is using
Apache-Overview states Storable Version 2.56
