Hello
I have a message on the page plugin that says
Deprecated: Assigning the return value of new by reference is deprecated in pluginmgr.php on line 560
my version of PHP is 5.3.2
Frank, if you want to ask some question in the english board you must follow the board rules an give us more details as explained in the doc ;)
Has already been fixed in r7318: http://coppermine.svn.sourceforge.net/viewvc/coppermine/trunk/cpg1.5.x/pluginmgr.php?r1=7174&r2=7318
