Support » Fixing WordPress » 500 internal error when trying to access update-core and plugins (WP 4.4)

    I first noticed something was wrong on 20th December 2015. My Wassup stats page showed “Too few records to print chart…” I remember that around this time I did some automatic updates (plugin updates and themes).

    I thought it was just the Wassup plugin, but today I looked closer and my plugins.php and update-core give 500 internal error. Sometimes when I click on “Themes”, I get this error too, but after the second click I can access themes perfectly fine. Also, I cannot access Settings > options-general.php (“Content Encoding Error”).

    I checked update-core and other files, and they’re modified on 20th December.

    I deleted the Wassup plugin, also some themes (I don’t use those anyway) from my server, but that didn’t help.

    My WordPress version is 4.4, so not the latest version. But I cannot update it.

    Does anyone have any idea what could be the cause and what to do? I never had any problems with WordPress up until now.

    Many thanks in advance!

  • Update: So I manually updated to 4.4.1, but the same problems persists (no access to plugins, update-core and options-general php).

    Hi there,

    Try to rename your “plugin” folder to something like “plugin-bak” and try again to access or load your site.

    Let us know how that goes.

    Thank you.

    Thank you for the suggestion, CureWP.
    I renamed the plugins folder to plugins-bak and the plugins have disappeared from my website, but I still cannot access the update-core, settings (general options) and updates on my Dashboard.

    …and now the Appearance stopped working: wp-admin/themes.php gives the same error:

    Internal Server Error

    The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    More information about this error may be available in the server error log.

    My website is working, but so what? No updates or changes possible. I have no idea how did that happened. Something must have gone wrong on Dec 20th (bad 4.4 update?) and I don’t have a backup copy. I have zero knowledge about these things, so unsure what to do next.

    Hi there,

    My WordPress site is running version 4.3.1.

    When I try to access the Updates and the new Plugins ready for adding, I get ‘Internal Server Error’ with this:

    “The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator, webmaster@handweavers.org.nz and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    More information about this error may be available in the server error log.

    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.”

    Not sure how to rename plugins folders if that needs doing.

    If you can help, that would be great.

    Thank you.

    Hi,

    I’m still having the above problems… please help.

    Have you tried these instructions?

    How to Fix the Internal Server Error in WordPress

    Update:
    10 days or so ago (April), my WordPress (4.4.2) magically fixed itself and all of the above mentioned issues disappeared.
    I can’t explain how that happened, since after those problems occurred and after my failed attempts to fix them back in February, I’ve basically left it be.

    After this joyful discovery, I was of course wary of upgrading to the newest version 4.5, but finally did, and everything appears to be in order.
