The search box over in the sidebar might get some use from you guys, but it probably gets a lot more from me, as I try to see what else I might have said on a subject.
While doing that sort of research Monday, I found a couple of old posts which didn’t bring up the topic desired at all but which, when served up by the Big G, contained extraneous information that happened to match the search. These were static pages; I sent up fresh copies, just in case. And then I went looking for a reason why.
Turns out that last week someone managed to drop a bogus redirect for search engines into .htaccess, and directed it to an encoded php command hiding in a little-used directory. I had WordPress pretty well locked down, but I’m thinking the problem was with FTP. It took me about two minutes to find the offending code and trash it. Passwords and such, of course, are being adjusted.
