 * Help!
 * For about the past week, whenever I try to log in to my blog, I get this message:
 * > Fatal error: Call to undefined function: wp_redirect() in /home/brykm2/public_html/
   > wp-content/themes/default/sidebar_old.png(457) : runtime-created function(1):
   > eval()’d code on line 456
 * My blog is still available to view, but there’s no longer an “Edit” link under
   each post.
 * Anybody out there seen anything like this? Anybody have a clue?
 * My host is LunarPages, BTW, if that helps anything.
 * I’d appreciate any help!

 * That’s… odd. I’d say you got hacked.
 * Look closely at your theme. It may have been altered by somebody else.

 * You mean you cannot login? I just looked at your site’s source code and it looks
   fine from here. You appear to be using a modified version of the default (kubrick)
   theme.
 * Just user FTP to rename that default theme folder and reupload the *original*
   default theme and use it. Maybe that will allow you to login. (Stranger things
   have happened.) Contact me offlist (view my profile) if you need help.

 * okay, hmm … i think i can do that …
 * i know how i can rename the folder … i’ll look into reloading the original theme…
   i’ll email you if i get stuck …
 * thanks joni, and thanks otto too … !

 * BTW, to answer your question, the error message above is what i got when trying
   to access my edit page (i.e. clicking my bookmark to [http://brykmantra.com/wp-admin](http://brykmantra.com/wp-admin)).
   I’ve been doing it that way for three years, so i never really give it much thought.
 * And now when i try the same thing, i just get a blank page, and it says “Done”
   in the status bar.
 * Oh, and another thing: I just renewed by domain name registration at Network 
   Solutions, about the same time as this started happening. Is that a coincidence,
   or might that be a factor …
 * Sorry i didn’t bring this up earlier, but it didn’t occur to me …
 * Thanks again!
