I am enabling an existing platform written in PHP to be delivered via mobile web browser. I am getting the "Cannot send Session Cache limiter - headers already sent" error.
First line of code is <? php session_start(); ?> This is the line in question.
Since it is for delivery on a smart phone, we have the standard headers:
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />
If I go to a flat <html><head><body> configuration, I can manage the sessions, but then of course I lose my phone enablization.
I am at a loss 3-4 hours of experimenting in.
Issue not in "mobile web", you just have to fix your error with headers. After headers already sent should be line, where headers sent.
Try to remove BOM symbol, try to use ob_start().
At least try to use search - headers already sent it's most frequently asked question in PHP.
