no related posts after re-insert database

hi,

i completly developed my site on my local host, offline.

the related posts worked wonderful, but after going online, there are no related posts anymore. there is only the slogan “No related posts.”

i changed nothing, i only import the database from my home maschine to the webserver. no errors, nothing.

only when i update a post, there will be a related post. but i can’t update all my 250 posts only for the yarpp plugin.

do i have any other options?

thanks a lot.
