Anne:
There are several 'myDEBUG-adm' log files, the content of the most recent says :

[21-Dec-2010 17:41:46] PHP Warning: htmlspecialchars() expects at most 3 parameters, 4 given in (*path hidden)admin/includes/functions/general.php on line 39

line 39 reads as:

return htmlspecialchars($string, ENT_COMPAT, CHARSET, FALSE);

I haven't notice anything malfunction, except the slide show.

Does any of the above pertain to the slide show?

Thanks,
Ken
