trouble with Login-Redirect v1.31 errors and code included please help.

[feyrerm]

I am relatively new to PHP so any help would be greatly appreciated. there seems to be a problem with my variable registration, but the first error  is an if else statement and I cant figure out why it fails because it shouldent matter if its empty. Its saposed to check to see if its empty and if so ...else. Please help if you can. Thanks.



here are the error messages.

I'm having the same exact problem. Ive been using the same code for other sites and the code worked perfectly on my local server and on another one, however as soon as I uploaded it this new server the code stopped working and I got these same error messages.
