WordPress Multisite blog doesn't work anymore

Hello there,

One of our blogs completely stopped working. Only the landing page is still accessible, but all other pages, sections (also the login page) etc seem to have vanished.

It concerns a blog that hasn’t been used the past weeks, so we have no clue what caused this mishap. Since the blog is inaccessible, I cannot restore it to a previous back up.

It concerns: http://blogs.fasos.maastrichtuniversity.nl/afterbabel/20142015/

Many thanks,

Sjoerd

    Hi there

    Do you cpanel? If so, then in some cpanel there are some automatic backup takes place. Would you please contact them?

    Also, check if you have any malicious plugin or code, if the plugins and theme from a trusted source or not – those are important.

    You also need to check with your host if your server got hacked by any way.

    Let us know how it goes. Have a nice day!

    Cheers,

    Ash

    Hi Ash,

    We don’t use cpanel here (Maastricht University), but Parallels Plesk Panel that is hosted on an internal server. Backup option isn’t enabled.

    Nothing has been changed for this blog for several weeks; in terms of content, themes, plugins. Everything worked fine until a few days ago. The only thing that happened before that, was a WP update to the latest version.

    Btw, we’re also experiencing problems with another multisite blog since that update. You’ve reacted to that one as well I see: https://premium.wpmudev.org/forums/topic/wordpress-multisite-blog-doesnt-work-anymore

    Cheers,

    Hi FASoS ,

    Hope you’re doing well today and thanks for your patience here:

    I visited the link you mentioned in the topic description and all pages are giving a 500 error. 500 error is a generic error and don’t give us too much information, so, we need to investigate further

    1) Have you tried to give a look on the server error_log to check the errors saved? Can you share it with us?

    2) Also, can you enable the debug flags adding the following codes to your wp-config.php :

    define( 'WP_DEBUG', true );
    define( 'WP_DEBUG_LOG', true );
    define( 'WP_DEBUG_DISPLAY', false );

    It will be saved to a debug.log file inside the “wp-content” folder. Can you share it with us?

    Note: Save the file as a .txt, because the .log extension is not allowed in the attachments.

    3) Also, I think this article may interest you too:

    I hope this information has been helpful. If I can help you in this or other related question, please let me know!

    Cheers, Luís
