"Go to Checkout" gives 404 Page Not Found Error

[MehYourFace]

I've been searching the forums for help w/ this issue but I can't seem to find anything.

Clicking on the "Go To Checkout" button gives me a 404 Page Not Found Error.

I stopped working on my website for a couple of months after a car accident and think the error may have occurred then. Unfortunately, I've since forgotten what was added/changed.

Please help! It will be GREATLY appreciated!

Hi Stevesh:
I added the "enable_error_logging.php" file into my includes/extra_configures folder but no new "myDebug" error file showed up in the cache.

I'm able to create a test user account and see the "add to cart" page, just no checkout page.

I removed the Debug Error-Logging file and followed the instructions under "b) Attempt to show errors on screen". This was successful in showing me the warning error: "Cannot send session cookie - headers already sent ...on line 108"

Now I'm following the tutorial on Headers Already Sent to see if that will fix it.

Will update soon...

The error is in the includes/functions/sessions.php file on line 108. Unfortunately, I don't know enough about PHP to know what should be changed...

Here is the source code from lines 102 - 114:

function zen_session_start() {
    @ini_set('session.gc_probability', 1);
    @ini_set('session.gc_divisor', 2);
    if (defined('DIR_WS_ADMIN')) {
      @ini_set('session.gc_maxlifetime', (SESSION_TIMEOUT_ADMIN < 900 ? (SESSION_TIMEOUT_ADMIN + 900) : SESSION_TIMEOUT_ADMIN));
    }
    $temp = session_start();
    if (!isset($_SESSION['securityToken'])) {
      $_SESSION['securityToken'] = md5(uniqid(rand(), true));
    }
      if (ereg_replace('[a-zA-Z0-9]', '', session_id()) != '') session_regenerate_id();
    return $temp;
  } 

In the file, "$temp = session_start();" is line 108. Any ideas on what might should be done??? I've never modified this file before.

Thank you in advance!

Found the source of the problem...

Warning: Cannot modify header information - headers already sent by (output started at /home/*******/public_html/store/includes/init_includes/init_sessions.php:89) in /home/*******/public_html/store/includes/init_includes/init_templates.php on line 78


According to the error message on the page, the problem starts in include/init_includes/init_sessions.php:90. I understand I'm to ignore the error in init_templates.php because that's what discovered the problem. Unfortunately, I don't notice any blank spaces, white space, or odd-ball characters in the PHP in the init_sessions.php file. (Probably because I'm such a newbie.)

Any ideas??

[MehYourFace]

Anyone have any input on the above code? There are no blank spaces before or after the PHP open and close tags.

Also, line 89 specified is: "$ssl_session_id = $_SERVER['SSL_SESSION_ID'];" under the "verify the ssl_session_id if the feature is enabled"

I'm at a total loss...

[MehYourFace]

I've updated to Zen Cart v1.3.9d thinking this would help the error go away...

No such luck. I'm still receiving the Page Not Found error.

[MehYourFace]

I'm so thoroughly frustrated and disgusted w/ this error...

Since updating to Zen Cart v1.3.9d, I can no longer see any errors from the Strict Error Reporting Log and the Debug Mod never pulled anything up for me. (Yes the files are in the correct spots... /includes/local/configure.php & includes/extra_configures/enable_error_logging.php) I even checked the error logs on my host's server and it came up clean and yet I'm still receiving the 404 Error.

I've been working on this all night and day and have yet to find anything that will help me solve this on my own. I haven't found any posts that can specifically say what solved their issue besides deleting white spaces in their PHP files, which I've done.

Please, if anyone can offer assistance, I would be most graciously appreciative. This is now holding up my dreams of owning my own business. I'm willing to beg for help. Beg... beg... beg...
