SA Redirect Warning: Cannot modify header information
Dear Web assist,
My SA login works great except on redirect to previous url where is turns up the error below:
Notice: Undefined index: HTTPS in /Volumes/My Book/Cura Romana/Dreamweaver/the body transformed back end/curaromana/WA_SecurityAssist/Helper_PHP.php on line 136
Warning: Cannot modify header information - headers already sent by (output started at /Volumes/My Book/Cura Romana/Dreamweaver/the body transformed back end/curaromana/WA_SecurityAssist/Helper_PHP.php:136) in /Volumes/My Book/Cura Romana/Dreamweaver/the body transformed back end/curaromana/WA_SecurityAssist/Helper_PHP.php on line 38
I read on a few forum posts that this warning can appear is I have white space in the php code. I have checked and I can not find any unwanted space. Not sure what is causing this. Please help, I have include the login page and the helper.php page below.
Many thanks as always for you help.
