Re:Erro no login
Too many errors on your plone site, i don't have the time to fix all.

Inside "portlet_recent", i replaced :
and added inside the catalog request
range : 'min'},
There is one other bug but it is better if you find a solution yourself. Go to http://biblioteconomia.objectis.net/manage_emergency to access ZMI
