I installed MOS some releases back and have been doing the upgrades as they come out. I started having a problem when I upgraded from 1.0.5 to 1.0.7. When I go to administer the site I get inconsistencies on the menus. For example, I can change templates but I cannot even see the option to change the main menu anymore. The same thing applies to components, some show the screens while others don't. I have tried uninstalling and reinstalling the component to see if it resolved the problem but this does not seem to do it. The strange thing is that "some" options under a specific menu will show while others will not. I do not get any error messages, the browser simply says "Done" but the screen is blank.

Any thoughts as to where I may start looking to resolve this problem?
