There was a security patch this weekend, which seems to have caused the issue.
I am not sure if I can fix it or not. I will look into it. However it appears that the vBulletin SEO URLS are now working CORRECTLY which they were not before.
A lot of current questions have already been discussed years ago.
I've recently been reminded that some very useful 2009 links don't work.
They are of the long format style.
I thought each upgrade fixed any such problem.
A couple of years ago the search engine went from poor to awful, so I'm no longer inclined to solve the mistery of where the link should go.
Still don't see a way to search for threads started by a given member.
There's some very valuable stuff posted by Linuxman, Stogie5150
, Pendragon,...etc.
There's one picture Iceberg posted many years ago, concerning a C band LNBF on an 84e, that's invaluable as a reference.
In some cases, I have put a pool of relevant links in member threads.
Don't see how to search for my own posts, either.
