Post Preview not Working

I had an issue with 404 errors resulting from attempts to preview. The site uses WordPress as a CMS, primarily using Pages with only one section using Posts (the message from the president, which is updated on a schedule).

I had set up custom permalinks, which turns out to have been the problem. An easy work-around was to change the permalink structure from /%post-id%/%postname% to /%postname%/%post-id%. It seems to be important to end the link with the ID.

This worked for me since the ID does not show on page urls, which were the ones that mattered, especially since the posts were referenced from within the template, so this did not ruin the ‘prettiness’ of the links at all.

I’m sure this is an unacceptable solution for many, if not most, WP websites, but I thought I’d put it out there.
