 * This is the ONLY plugin which promises to do exactly what I need but when I try
   to activate it I get his message:
 * Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /home/sites/clearskydesign.

 * Ok – I think I’ve fixed this using MM_FileList::$attsKeyTemplate instead of $
   this::$attsKeyTemplate,. Can you try again?

 * Hi. I no longer need the plugin but neverthless have just tried to install for
   the purpose of testing your amendment. Sadly, it still doesn’t work for me – 
   could be a comaptibility issue with the theme or something.

 * Please don’t feel the need to fix this for my sake any longer, though I hope 
   the recent changes fixes it for others.

 * Hey Dan,
 * That’s really strange that it’s not working. I almost think you must be running
   a different version of php if (considering the errors shown so far). That line
   194 is using the array_map function which only works in version of php 4.06 and
   higher. By any chance are you running an earlier version?

 * Ok – just to followup on this. I checked your site and it’s running php 5.2.17
   which doesn’t like anonymous functions in array_map() which was causing the issue.
   I’ve cleared that up so version 1.2 should be perfectly usable.
 * Sorry again that the code wasn’t working for you! I’ll make a point to check 
   it out in multiple versions of php going forward.
