Admin Blank Page -please help-

Recommended Posts

I just set up my server w2k3 IIS after a hard disk failure, this time with php 5 instead of php 4.3.

 

Uploaded a back up of the store and a back up of the data base.

 

The catolog pages looks to work fine, but if I try to go to admin www.mystore.com/admin all I get is BLANK page

 

any ideas?

 

thanks

I turned on php error logging, and these were the errors:

 

Warning: session_start() [function.session-start]: open(/tmp\sess_2d51a00518534f7100c7c7af0e44525d, O_RDWR) failed: No such file or directory (2) in C:\Websites\mystore.com\web\admin\includes\functions\sessions.php on line 67

Okay, two errors to deal with. In both of your configure.php files make sure that the last line reads 'mysql' where indicated - storing sessions in the database and not in files. Next, read the '$this in uploads.php' link below my name.

I spent the past two days in total frustration trying to figure this one out - thanks my new site now has an admin!

FYI to anyone else experiencing the blank admin problem, I was able to fix it on one particular server by removing "www" from the URL listed in the admin/includes/configure.php. For some reason, the server wasn't liking that being there.

Hi -

I'm having the same problem: my admin page just comes up blank with no errors displaying on it after trying to install version 2.1 one page checkout addon.

 

I don't know how to turn on the php errors. Can someone help me figure out how to get these errors to display so that I can figure out where the problem is??

 

Thanks for your reply

Liz

/admin/includes/application_top.php

 

// Set the level of error reporting
 error_reporting(E_ALL & ~E_NOTICE);

Try this instead:

 

// Set the level of error reporting
 error_reporting(E_ALL | E_STRICT);

BACKUP THE FILE FIRST!!!

 

Change it back when the problem is found and fixed.


If I suggest you edit any file(s) make a backup first - I'm not perfect and neither are you.

Ok, thanks. I did that and tried to login again to the admin, but nothing changed. No errors, just a blank page. Is there somewhere else I need to look to find the errors? Any ideas on why the blank page only comes up?

See if your hosting service has an error log for your site you can examine.

 

If not, see if they can setup one for you and tell you how to find it.

 

There is one other method I can think of but it's very "tedious"...

:blush:

ok in includes/application top.php

find this code if its not there add it should be right near the top of file

ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
error_reporting(E_ALL);

 

now simply create a text file called error_log.txt in root of your stores folder

now give that file write permissions 666

any errors should now be writen to that file

Hi Wilson

 

Them headers alreay sent is most likely white spaces in C:\Websites\mystore.com\web\admin\includes\functions\sessions.php

 

delete any empty lines before and after the ?> at bottom of the file

 

also make sure this folder is not read only /tmp\

Ok, I did that and then put the txt file in the root of the store folder. I tried to login and I'm still getting the blank page. I checked the txt file but nothing is written in it.

Hi Liz

 

Host has any error log ? try this goto admin then replace index.php with login.php see if you still get a blank screen, if so try uploading admin again minus catalog/admin/includes/configure.php file delete that file before upload

Hey Steve, this is a pretty good tip!!!

;)

 

I finally got it to work but I had to replace dirname(__FILE__) with the absolute file system path to the log file.

The code works "as written" if you create the error log file in the same folder as the application_top file you edit.

 

dirname(__FILE__) returns the folder path to the current file (application_top.php).

 

Gotta' love this tip!

:lol:

Hi.

 

Also, Adding

 

ini_set('display_errors',FALSE);

 

Will prevent the Errors from being displayed.

 

So it can be used Shop Side.

Thanks Steve - that worked and now I'm getting an error when I got to http://mysite.com/catalog/admin/index.php - the error I get is below:

I'd bet my last dollar you've accidentally copied /catalog/includes/header.php into the /admin/includes folder...

Replace E_STRICT with 2048 in the code that Jim suggested. This is not important to your original problem, but might as well make this error and the next two go away. We could try to figure out why it doesn't like E_STRICT, but I don't know that it matters.

Both of those are caused by the E_STRICT error. It sends output, which breaks things that assume no output until later.

Always backup before making changes.

This is what an unmodified osCommerce-2.2rc2a /catalog/admin/includes/header.php looks like:

The one from /catalog/includes is much longer and starts like this:

Thanks Jim - you were right. I had the wrong header.php file in the admin/includes folder. I've replaced it now with the correct one and I think we are getting closer......

 

now when I try to login under catalog/admin/login.php I get this error message above the username and password fields

I was kinda ecstatic that I saw the login boxes, but when I tried to login I get this message:

I'm not sure if I understand what other code I was supposed to modify from the other reply - maybe that's why I'm still getting errors.
