This is note regarding changing your theme.
If you notice items are missing after a theme change.
Change back to the forum's the default theme.
Make sure all sections are expanded by using the little arrow icons in the top left and right corners of each section.
They should point UP so you can see all of the content on the page.
Then choose your new theme again.
The sections should now be visible.
The reason this happens is that some themes don't have the option of collapsing and expanding sections but they still conform to your chosen preferences in the default theme.
