My wordpress blog is in its own directory (/blog), and if you go to the main site, it pulls up the blog as the main page. When I update any theme, everything updates fine. If I do something like add a widget, everything updates fine. If I take away or delete a widget (using the widget as an example, it's true for anything - pictures, background, ect), it updates everywhere except the main /blog page. If I go to the plain .com of my website, it shows the update, and then on all of the pages it shows the update, just not the main /blog.
Can someone help me on way the /blog isn't updating?
