I have a problem with my website. The content of some posts gets doubled. It doesnt get that way right away but happens about 1-2 weeks after the post was made (see http://www.tango.no/blogg/har/a-lage-bevegelse-i-haret/ )
I did have this problem before but thought it was only something that happened when I re-innstalled wordpress. But now it has happened again.
Anyone who knows what may cause this?
