This happens on any forum where the forum width is restricted and there is not enough space left for the tabs to the left of the search box, which then stack up over each other.
One solution is to remove the styling instruction for the search box to "float:right;". (It will shift the search box to the left but makes sure everything separates properly.)
Try this:
1. Click the "See how NAML generates this page" link on the page affected.
2. Scroll down the page to line 33 in the code
3. Click the link: user_nodes_search_box
4. Click the "Override this Macro" button
5. In the edit box remove the text:
float:right;
from Line 2 and save the changes.
