Hello, I have this weird issue with the posts - for example, after google caches a post of mine, and I find that page in the search - I click thru and I get the nothing found page, like if google made that particular url up and it was never a post url of my blog, I use feedwordpress, the duplicate posts filter of feedwordpress - are there any issues know with them? My urls aren't teh default wp urls - I set wp to put the post title in the urls so there's lots of keywords there - I even saw a case when somebody came to a post and after that there was page not found in that url - I then dicovered that the url changed somehow and there was one word added to it and it was accesible that way, added by feedwordpress I think - as he updated the syndicated content, making a new url for that post - but why erasing the older url of that post... This happens older and newer posts alike - could that be that posts are deleted on their own? Or what else might be causing this?
Thank you in advance!
