Changes on certain pages not reflected

I’m making setting changes on certain pages such as my blog page that are not showing up on the site. If I change the page from fullwidth to rightsidebar and save, the page still shows fullwidth. This is the same reaction to any changes I make to the page. But this does not happen on all pages, just random ones. When I go back into the page edit mode, the setting do in fact show that they page is set to rightsidebar.

I’ve already set the WP_MEMORY_LIMIT to 128M. I’ve also made sure that there is no cache applications installed.

What do I need to do to be able to update/changes my pages?

Thanks,
Anthony
