Can't login to specific subdomain after update to WP 4.5

Hello.

I've just updated to WP from 4.4 to 4.5.1, which made most of my network crash. I've updated all plugins and themes now and everything seems to be working, except a specific subdomain:

http://eurasierklubdanmark.webinnovate.dk/

When i try to login i get Error 500. The website works fine, its only login that gives issues.

I haven't found any other sites that doesn't work so far. I've granted access so you can take a look.

Thanks!

Best Regards,
Rasmus

    Hello Rasmus,

    Could you check again support access because none of your registered sites has it open.

    Also do you know if this particular subsite use plugin that is not used on different subsites - or it has custom theme?

    If you can please try to run a quick plugin/theme conflict test as illustrated in getting support manual (flowchart). Let me know how it goes.

    Hello Rasmus,

    Please enable debug mode in your WordPress and then try access this subsite - it should generate error that will tell us why this is happening. To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

    define('WP_DEBUG', true);

    In order to enable the error logging to a file on the server you need to add yet one more similar line:

    define( 'WP_DEBUG_LOG', true );

    In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

    Depending on whether you want your errors to be only logged or also displayed on the screen you should also have this line there, immediately after the line mentioned above:

    define( 'WP_DEBUG_DISPLAY', false );

    The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it. I would need then to see contents of the debug.log file - so please paste it to the text file and attach to post.

    kind regards,
    Kasia
