# WordPress Migration – Strange Behavior

 * I’m in the process of migrating an existing live HTML site to WordPress. All 
   development and content migration from the current site has been done on a local
   development instance.
 * Before formally going live with the WordPress migration, I’m testing out the 
   migration process on a subdomain of the production site. Everything has gone 
   well with one notable issue.
 * For some reason, a small percentage of pages, posts and categories will not display
   once migrated. An error, “The requested document was not found on this server.”
   appears when clicking on a link to these items. They all appear and behave fine
   from within WordPress, the issue only appears when looking at the website.
 * Less than 5 out of 400 posts, 2 out of 30 categories, and 2 out of 10 pages behave
   this way. The rest work fine.
 * I’ve even gone into MySQL to see if there are any glaring differences between
   the posts/pages that work and those that don’t. All data seems to be consistent.
 * It would be a much easier problem to solve if all content behaved this way. I’m
   really scratching my head over the seemingly random nature. I’ve even redone 
   the migration several times and it’s always the same posts, pages and categories
   that fail.

 * Yes, re-saving permalinks was one of the first things I did after the trial migration.
   I’m wondering if WP saves permalink mappings elsewhere besides the database? 
   Perhaps the few posts/pages/categories that don’t work are “stuck” somewhere.
 * I’m going to keep researching but any additional input is always greatly appreciated.
 * Thanks!

 * Do you have any caching plugins?

 * Nope, no caching plugins – thank you for the input.
 * Just started over with a fresh install to retrace my steps. Using the default
   theme and before setting permalinks, all imported posts, pages and categories
   appear fine. Once I set the permalink custom structure to /%postname%/ is when
   the same couple of pages and categories produce the error: “The requested document
   was not found on this server.”
 * Doing more research on the permalinks mechanics…

 * The issue was with caching – although I’m not sure why.
 * My default browser is Safari. For kicks and giggles I viewed the test migration
   on Firefox with no issues at all. After emptying the Safari browser cache, all
   posts, pages and categories appear fine.
