Link in code is correct but redirected to "Page not found"

1st problem:
Any idea why are the links in vbulletin search results redirecting to ａwhite page with "Page not found" text?

I am using the latest vbulletin and vbseo (default settings).

2nd problem:
I have generated a dynamic image link for every thread so that anyone is able to add these images into their websites. Clicking on the image link should be able to link them back to the particular thread.

However, anyone who clicked on the image link are redirected to "Page not found" page. The weird thing is that when i copy the URL manually from the image link and paste it to a new browser window/tab, the link is working fine.

E.g.

Code in template:

Code:

<a href="${current_path}showthread.php?t=$thread[threadid]" title="Money Making Forum">
<img src="${current_path}advancedranks.php?showtopic=$thread[threadid]&image=1" border="0" alt="Money Making Forum" /></a>

Code displayed to users for them to add to their website:

Code:

<a href="http://www.moneyfanclub.com/hyip-forum/4516-lgpro-www-lgpro-com.html" title="Money Making Forum" target="_blank">
<img src="http://www.moneyfanclub.com/advancedranks.php?showtopic=4516&image=1" border="0" alt="Money Making Forum"></a>

Any idea on how to fix the two "Page not found" problems?
