I have been getting completely random 404 errors while using the after sales of WordPress. These errors are for completely legitimate admin pages. The workaround would be to refresh the page – which often works the next time around.

I have seen this issue reported elsewhere but no solution. Wondering if anybody here has plans.

Ideas:

  1. Perhaps you have made any modifications towards the htaccess file?
  2. Are all of your plug ins modifying htaccess?
  3. Consider the servers access.log and error.log files to ascertain if there's any odd behavior.
  4. Look at your version of php and version of wordpress and make certain they are much less old/too new.

The intermittent-ness is odd, though. I've not experienced this while using latest version of Wordpress and php 5.

Could it be a lot-balanced atmosphere? You might have these pages not used to a few of the servers within the farm.
