I first installed on the local installation ( XAMPP ) of the site I manage and it worked wonderfully after tweaking it a bit with the options provided. I then naturaly installed YARPP on the online site which is the same ( same files, same database but only online ) site. And the results are not the same at all. It seems that online the results returned are very weird. For example localy if a post of a tutorial is displayed, naturally the related posts returned by YARPP are tutorials ( eight of 'em, well all , with a score of about 10 to 20). Online no tutorial is returned, only 2 posts not really related with a score of 9 and 6.
I'm very puzzled by this behavior, I double checked to make sure every option is the same localy and online, I tried &action=flush to reset the cache but no success.
If someone can hint me to something, I'm rather sad, I was so glad YARPP worked so well !
