This seems to be a common problem but I searched the forum and tried a few fixes and haven't been able to resolve my issue. Recently I noticed that 2 of our pages won't load and bring up the 404 error (using the standand twenty eleven theme). For example:
Yet the other pages we have set up work, as do all the permalinks to posts. The pages that have errors loading are fine in the back-end but for some reason don't go through. Is there any reason for this? I haven't made any big updates to wordpress versions of plug-ins that I can think of except for SEO by Yoast (updated today), but didn't change any of the settings and again only some pages don't load.
