There's a bunch of reasons:
 * 1) Page numbers may be cached by your computer. You'll have to clear your cache to delete the old version of the page.
 * 2) Page numbers may be cached by Wikia. Add "?action=purge" or "&action=purge" (use the & if there is already a ? in the URL) to the end of the URL.  You may have to wait a minute or two for the page to purge
 * 3) Page numbers only count those in the Main namespace. If it counted templates, mediawiki pages, help pages etc. the number would be in the hundreds, even for a new wiki.
 * 4) Page numbers are sometimes off a bit. There's really not much you can do about this.
