You may have seen, around the wiki, the content of pages randomly doesn't display. Apparently, this has been a pretty common issue for some time, but I've only noticed it happening recently.

If a page is blank but, when you press "Edit" or "View source" you can see it has content, you need to purge the page. You can do this by going to the URL and adding "?action=purge" to the end of it (without the quotes). The page content then should display.

If you don't want to bother typing that in every time you need to purge a page, you can import the PurgeButton Javascript tool (there are instructions on how to do so at that page). This adds a "Refresh" button to the edit dropdown menu which, when pressed, purges the page for you (as well as your browser's cache).

Thank-you for your time.
