Undefined index errors

[Yonkey]

I'm suddenly getting a lot of undefined index errors and I have no idea why!  I didn't touch any of the files its reporting.

8: Undefined index: ip
File: /Sources/LogInOut.php
Line: 227

8: Undefined index: ip
File: /Sources/Subs.php
Line: 1113

8: Undefined index: local_time
File: /Themes/default/Profile.template.php
Line: 221

It's like it suddenly can't see my IP.

Either old language files or old sources.  Please try a detailed version check.

I can't run the detailed version check because the php has a safe mode restriction.   

Also it's very odd, because I wasn't getting any of these errors yesterday morning.  The only file I changed was Load.php and index.template.php which are both back to how I had them originally.

UGH!  I just realised I reverted the Load.php to the 4.0 version and not the 4.1.  Replacing it with the proper version of the file fixed it.  lol, I feel like such a loser.   

Sorry to waste everyone's time.
