Sorry. Is there a reason why those exact links work through another forum and not this one?
It looks like they were copied from another forum after vB
shortened them. If you put in a very long link in your original post the vB
code the forum uses shortens the link for display purposes
, putting in "..." for a long string of characters, like you see after the "a3" in your links. The resulting links then look shorter than they really are, like yours above.
However, if you put in an original link with those "..." characters in it, then that becomes part of the link, and the link is no longer valid and won't work.
So, what likely happened is you put the full link in your original post on another forum, and the vB
code of that forum shortened the link just for the display, not for the execution of the link. Then, you copied the shortened "display only" link, which wouldn't work here because it isn't the full link, and has the "..." characters instead of the actual code.
Hope that's clear
