TOPIC: can not create event from frontend

hello,

i want some users to creat events
I have à link = manage events = /index.php?option=com_dtregister&view=eventmanage&layout=list&controller=eventmanage&task=list&Itemid=1204
on this link there are some buttons : all are linked to : index.php?option=com_dtregister&Itemid=1204

when i activate seo-sef in joomla it is the same thing

is this a problem you have already seen ?

thanks serge
