We have just moved a wordpress site to a new hosting company. The site is setup and work the same in both locations, the only problem is on the new site only 5 posts per category are displayed. Changing the amount of posts in Options -> Reading has no effect at all. This would be fine but there inst even a "show more" or "<- older posts newer posts->" at the bottom of the page.
I dont think there has been any customisation done, and anyway the sites are identical so if there were it should be the same on the new site too.
