    I have my debugging mode set to 1 and it is not displaying any errors. I just get stuck on a blank white page when trying to login. Here is the url it gets hung up on: http://www.dapacreative.com/console/index.php?S=0&D=cp&C=login&M=authenticate

    I have had my site in EE for awhile now and have not changed anything. One day I logged in and this is what I got.

    I am having the exact same issue.  This past Friday, everything was working, but today, every login is presented with a white/blank page.

    I have seen this as usually cookie or session related.

    I originally thought so, but the problem wasn’t solved after I tried 4 other browsers.  Are there cache files I could delete on the server side perhaps?

    I deleted everything in /cache/page_cache as well as in /cache/sql_cache, but without luck.  Will attempt a server restart to see if this resolves the issue.

    This is an error noticed in the server logs, but I am not sure if this could be the culprit:

    PHP Fatal error: Call to a member function get_upload_preferences() on a non-object in /.../expressionengine/third_party/wygwam/ft.wygwam.php on line 643

    I looked further into this but the suggestions don’t appear to fix it and I am still getting the blank page after login.  It is so weird that even with DEBUG turned on I am not getting any messages to display on the page itself.

    White Page of Death

    Say your EE site’s front-end or Control Panel is completely white. You can’t exactly get help from the Output Profiler or Template Debugging if the page doesn’t even render anything. The ultimate “debug switch” can be found in your site’s index.php files. If your white screen of death is on the front-end of your site then crack open that index.php file in your editor and look for this bit of code:

    /*
    *——————————————————————————————————
    *  ERROR REPORTING OVERRIDE
    *——————————————————————————————————
    Below that you’ll see a paragraph explaining exactly what you’re about to do. It’s important to note that “[e]nabling this override can have security implications. Enable it only if you have a good reason to.” So, what you’ll want to do is change the value of $debug to 1. Your code would look like this:

    $debug = 1;
    If your white screen of death is on the Control Panel side of things you need to do the same thing described above - except with the system/index.php file or your masked CP file (which might be something like admin.php).

    This will effectively “turn on” error reporting to everyone. I only use this locally because it often gives details on application and database structure in the error messages. Regardless, it is a very helpful tool if your page is rendering nothing at all.

    Was there ever a resolution to this? I have the exact issue with my admin page.

    I’m having the same issue after upgrading from 2.6.1 to 2.7.3, I attempted all the fixes suggested in the thread but I still can’t get the Admin CP to show. Debug is enabled but I am not seeing any error messages, it just sits and tries to load the Admin CP for like 5 minutes and then times out.

    Any ideas? Thanks!

    *UPDATE* I downgraded back to 2.6.1 and updated my Pixel and Tonic’s Field Pack extension and then upgraded to 2.7.3 and everything is working now.

    Is there a proper solution for this issue? I have been struggling for days.
