category blog links return 404's

Hi Andrea,
Please can you help, I've got a menu that links to a series of category blogs, the resulting page links seem to be generated by custom properties and all the links return 404's if SEF urls are turned on.

Example: First level menu links to www.future-agricultures.org/publications...theme/climate-change - this link is fine
then in page links are generated as various item ids
www.future-agricultures.org/search-documents?id=xxxx - all these links are returning 404's, any idea what may be causing this and how I can fix it?
It all works fine with SEF urls turned off!
Thanks
Sara

Those don't look like Joomla category blogs items. According to your email they are DocMan2 documents. Also the 404 message is generated by DocMan extension.
I'm confused.
Could you please let me have those urls (even in private form) in non SEF format. That would help.
