Admin crashes / inaccessible (HTTP error 500 (Internal Server Error))

  • My WordPress Admin crashes randomly on various pages and I can not determine what the trigger is:
    At first I thought it happened when I activated a certain plugin, but even when I turn off all plugins (through phpMyAdmin, since the plug page is not accessible) and go to ‘widgets ‘, or to ‘update‘ or even the dashboard, I regularly get a HTTP error 500 (Internal Server Error).

    Earlier I updated the WordPress installation (when I was able to access the update page), I put the php.ini to 64Mb, and later I have a new, empty. .htaccess created. Unfortunately all attempts without success.

    Can anyone help me on the way to solve this problem? Thanks!

  • I have had the same issue for a week or so. I have the latest WP. It started adding a plugin. I can’t save the menus page and sometimes pages won’t save.

    i’d suggest setting WP_DEBUG to true in wp-config.php
    and check the server php errors log

    also, maybe the upgrade hasn’t gone well…
    personally, i prefer to upgrade manually
    reinstalling all* wp files could help
    *except wp-config.php and wp-content, of course

    for resetting all the plugins, via ftp you can rename the folder to plugins.old, and create an empty folder plugins

    after WP is running again, delete the empty folder and rename the old one back to plugins

    I have also experienced the same problem: erratic Internal database error (HTTP error 500), plus erratic Error connecting to database. I get these errors since upgrading to WP 3.2 trunk, aprox since the beginning of this year.

    I’ve reinstalled manually all my wp-admin/ and wp-includes/ files, plus the ones that come along with wp-config.php (outside subdirectories). I have several plugins, but also I upgrade them manually.

    I’m in dispair because the possible cause of these erratic errores is almost impossible to identify; I cannot look at Mem Load plugin (or similar) when the problem happens, because no page of WP is then available, nor the front page or the desktop!

    Is there a strategic to troubleshoot this problem?

    I’m not the admin of the server where my site is hosted.

    Thank you very much brasofilo. You put me on the right track, and the website is working again.

    First I copied the WordPress files over the old fiels, but after putting my old plugins back the website crashed again, so I removed all plugin files and reinstalled them by hand and now it is working!

    nice to hear, birdy10!
